hmmm O2 damage to reduce altitude aka make it easier to catch bombers to destroy them. OP thinking cartoon pilot breathing cartoon oxygen will make cartoon plane fly lower 10,000 feet.
come on Kenaii its a cartoon game.
. do like everyone else does climb to 30k shoot at bombers maybe hit one or to get shot down for you're trouble.
nobody said you had to chase bombers, but if you limit a players game he/she's not going to be playing much longer. if you don't want to fly to 30k then don't, but don't try to make a player play you're way.
