Remove it and they go to another ride and the effect is unchanged.
That is unless one removes(or rather, regulates - "removing" a plane via punitive perk costs, is not the same thing as lightly perking them for regulating them) a total 'section' of certain fighters above certain performance levels, so that the very style of gameplay may change - currently, as I see it, the "MA style" of combat is a result of certain planes being interdependant on each other.
Planes being interdependant on each other is not a bad thing, but however, when those are the few plane types that are qualified for variety of purposes, being excellent in almost every category, the problem rises that practically other planes are rendered obsolete.
.........
La-7, P-51D, Typhoon, N1K2, Spit9 - these are all you need right now.
For jabo and suppression, the P-51Ds and Typhoons carry out the task with more ordnance than most of the jabo planes, far better survivability than most bombers, and then they can also immediately switch to versatile fighter roles after ordnance is dropped.
Mid to high alt fights, the P-51Ds used en masse takes the cake.
Low alt engagements and suppression, the La-7 does it all.
And the backbone of air power, the planes used in the 'grunt' role of air combat, chasing down slow planes or engaging other 'grunts', with high attrition levels - Spit9 and N1K2. These are planes that have exceptional maneuverability and yet, have decent speed(The N1K2 and Spit9 considered slow planes? Probably, to those who regularly use G-10s, D-9s, La-7s and P-51Ds, Typhoons. To the other planes below the "1944" levels, they are fast enough to be a big threat). Of those two, the former is a bit better suited for mid-high alt performance, and the latter can take on a jabo role if required, with four cannons of 900 rounds of ammo.
...
The combination of the above mentioned 4~5 planes(which, also happen to be the 'big four', except the Typhoon(if one considers jabo purposes, the Typhoon probably joins the 'big four' in usage)), is the exact element of their overusage. The 'big four' are the 'big four', because combination of those four, is the key to winning the land-grab theme surrounding the MA.
Then what about the superior numbers, alt-monkeying, running at the sight of co-E plane crap that's been going on? Simple.
Since all of the countries are now using that "Big four Combo" regularly, apparently there's no advantage gained in the combination of other plane types - thus, the advantage is earned by sheer numbers.
Since the "Big four combo" is so fediddlein' lethal, now, nobody, not even the vets, can be sure that they can meet a plane and win against it quickly in a major battle zone. As soon as you get that one guy, a La-7 comes on you co-alt, a P-51D drops down from high, and the Spits and N1K2s are waiting for you down low!
Either you stick to that "SA" thingy like the ticket to heaven at Armageddon's Day, or you become a victim, and at the same time, the perpetrator of it.
..
So, what about the other planes? The G-10 and the D-9?
These are probably the only two planes which can vaguely substitute the above roles that the P-51D and the La-7 plays. However, the huge difference in armament(thanks to that long-range aspect of Hispanos and .50s) makes them crappy substitutes at best, not to mention they are both no match in the multi-purpose category(too limited in jabo role).
So, basically the G-10 plays as a substitue for the La-7, but due to their insane climb rates, limited ammo and sucky weaponery, and special 'gadgetry' such as the gun pods.. they play a more defensive version of it. The D-9 plays the mid-high alt substitute role for the P-51D. Thus, these become the only two planes really worthy of considering use in the MA environment.
The P-38L, is a cross-breed between the P-51D and the Typhoon(in efficiency as the MA fighter) - heavier jabo loads, limited "running" capability, but better conventional dogfight capability. These show up when either they are suicidal, or the target field is already suppressed.
...
So seriously, will they go for another ride when the "big four" is perked? Yes, with simular results. The 'accident' in the MA, where Spits couldn't take off in Bugisles, showed that the Spits move on to N1K2s. People will move to the crappier substitue versions of their former La-7s and P-51Ds, but still, the results won't be too different.
But when the entire "section" of late war planes are perked?
Some say diversity cannot be reached by perking or regulating. But they are wrong.
The perking of the F4U-1C, is a testament to that. The F4U-1C is a four Hispano armed plane - which adds a vast advantage to its A2A capabilities, which carries 6 rockets and 2000lbs ordnance, can take off from a carrier, and also is one of the fastest planes on deck(slow acceleration and limited WEP, but the F4U-1D and the F4U-1C, is faster than the Bf109G-10).
It was a "one-plane-do-all" fighter.
When it was perked, what happened? Since no other plane has that kind of capabilities, it's role in the MA is now carried out by three different planes - P-51D, La-7, and the Typhoon! Also, in carrier ops, it's role is split into three by the F4U-1D for jabo, and the F6F-5 and the Seafire for pure A2A suppression. In short, the F4U-1C alone, was doing the job of 6 different fighters in the MA.
With the perk costs, increased risk, and added correct weight, it is now 6 different planes that carry the job that once, the F4U-1C did alone.
That explains why we'll never see a single plane doing 20% of all the kills in the MA ever! And that also means that 20% is now not the standard on which 'overusage' should be judged upon. Relative monoploy is what should be considered.
8 points for the F4U-1C gave way to 6 different fighter types in the MA. Therefore, perking some of the "late war fighter" section, should also be able to give way to other fighters by splitting the role which once one fighter could do alone by itself.
Perks do increase diversity.
Regulating the total section of late war fighters, which is consisted of the "Big four" plus its substitutes, will force the overall planeset into an era prior to the emerging of the "Super planes", where realtive performance margins are better balanced. Not to mention that also, the roles formerly carried out by them(which was once carried by the F4U-1C alone) will also split into other plane types - jabo role to the dedicated jabo planes, fighter role to the pure fighter planes.
