as long as achievements and perks are applied across all of the main arenas, there is way too much potential for gaming the game.
everything you listed is a "grinder achievement" Fester...
dump this one...
fire 5 millions rounds of ammo... Hit an enemy player or object with 5 million rounds of ammo
change these to be more specific...like bomber hangar, fighter hangar, strat object, town object, soft gun, hard gun, etc...
fire 10,000 rockets... Hit an enemy player or object with 10,000 rockets
drop 50,000 bombs... Hit an enemy player or object with 50,000 bombs
bail out 500 times... bail out of an airplane crippled by an enemy player 500 times
aren't there already achievements similar to these already?
Fighter:
Get 2500 kills in a carrier plane... get 2500 airplane kills in a carrier plane
Get 2500 kills in an early war plane... get 2500 airplane kills in an early war plane
Get 2500 kills in a mid war plane... get 2500 airplane kills in a mid war plane
add to fighter...
Get 2500 airplane kills in a late war plane
Get 2500 kills in a ww1 plane
those would be a little better if they were more specific to plane models/countries...like 2500 airplane kills in an f6f.
