Most of these issues have already been debated elsewhere ad infinitum, but I still want to respond to them. In the order that Pyemia originally posted:
1) N1k - was a great plane in real life, yes it turns better than a spit in here but it really did by all accounts. Takes more damage than a 190? I dunno, thats open to debate. Hard to tell in here which takes more damage. N1k seems to die easy enough most of the time though. Dives better than a jug? Are you out of your mind? There is no way. Try this experiment anytime you like. Take a friend to the training arena, one of you in a nik and the other in a jug. Climb to 10k and then both dive at same time, see who runs away. P-47 wins hands down every time just as it should. Climbs better than a P-38? I dont know about that either. I suspect that the P-38 has a better rate of climb while the N1k probably has better Angle of climb. Havent tested that personally though. And just how do you get that it has better guns than the tiffie? Thats ridiculous. To me the guns seem quite similar as well they should since both planes are using 4 20mm cannons. The British guns should be slightly better but I dont know of any way that you could verify this one way or another within AH. Landable on a CV? Of course it is. I can land practically anything in here on the CV. In real life it was intended to be a carrier fighter anyway so no surprise there.
2) Spitfire flight model? No comment because this area is just too subjective. I think that the spits seem to perform pretty much as I would expect them too but this will just degrade into an "im right, no im right"
type of an argument without any means of backing up claims.
3) La-7 is far from unbeatable, they are fast down low but other than that not so great. There are perked planes that are faster. As has been stated repeatedly before, if the La-7 is perked than people will just move to the next fastest fighter, probably the P-51. Then you will have the same argument with that. I personally would like to see some of the late war uberplanes lightly perked, but its not that big of a deal. Certainly never makes me consider leaving the game.
4) GV damage models. If you read histories of WW2, European theatre, you will find that US fighters scored many kills on tanks with their .50 caliber guns as well as with rockets. The .50 caliber MG bullet would penetrate almost all WW2 tanks from above and in some cases from behind as well since armour on tanks is much thinner there. Even the vaunted Tiger tank could be crippled or dispatched in this way. Even today, .50s are used against armoured vehicles of every type except main battle tanks. One USMC sniper in Desert Storm destroyed two Iraqi armoured personnel carriers with a .50 caliber rifle. These APCs were armoured on a level similar to some WW2 tanks. As far as killer bushes go, I agree that the little bushes shouldnt prove lethal to a tank, however, a tank cant just drive around the countryside knocking down all in its path. My dad was a tanker and he has numerous pictures of tanks getting stuck and disabled by terrain. You cant drive around with impunity in real life in a tank, you have to watch where you are driving, so it is in here. I have never lost a tank in here to killer bushes even though I drive ground vehicles sometimes. The reason I dont is because I watch where I'm going. Its quite easy.
5)I agree some on this one. I dont like having icons either, not just range icons but icons period. However I can see that they are a necessary concession in the MA at least. I would like to see them turned completely off in scenarios though. So yes they are a gameplay concession but a very necessary one in the MA.
6) suicide attacks. I dont think that suiciding is as prevelant as many people think. I think most of the time people go into a situation fully intending to survive but die in spite of this. I cant recall ever flying into a situation where I intended to get shot down but it happens quite frequently! Suicidal? Of course I enter some situations that I would probably not enter in real life if I were in the same but there is really no way to prevent that short of the electric shock from joystick that J_A_B_ suggested. Even in paintball, where there is a painful deterrent to prevent you from risking your hide needlessly I do things that I wouldnt do in real life. This is unavoidable. You will never find a simulation anywhere that this doesnt happen. Again, like so many of the other things, its not all that big of a deal, certainly not a reason to quit the game entirely. By the way, Japanese kamakaze attacks were pretty effective. They sunk and damaged an awful lot of USN ships and caused destruction far out of proportion to their numbers.
The bottom line is that I cant see any of these gripes as giving much of a reason for quitting. If these things bother you, than by all means quit, but I defy you to find a better simulation anywhere. This one is definitely the most realistic MMO WW2 sim yet.
