I think a 5pt perk would at least deter the suicide dweebs, and make them think a bit about actually trying to live through a fight. The folks really wanting to fly the bird wouldn't be upset by that small amount, much like the C-Hog's. While it may make nubs think twice about upping it to auger in while vulching or porking ord/troops.
Ahh, here we have that "educating" argument again. But it will fail. If they can't Ho, auger/pork in a La, they will just take a Typhoon, which has better payload and cannons anyway. (In fact, a LA-7 going on a pork run is a rare sight, for very obvious reasons)
Somehow I often have the feeling it's just a "I don't like it, I don't fly it, let's perk it". (And I'm afraid more often than not that dislike is just a part of AH socialisation, a parrot syndrome and a quite convenient excuse for own shortcomings)
There is no reason to perk a plane that hasn't any unbalancing influence on MA at all. LA-7 ith it's msierable range shouldn't be perked (as well as the Spit XIV should get it removed

)
