I'm strongly against any artificial performance limits to guide gameplay into way perceived "right" direction. Could a bomber open the doors and drop from 1k? Why should our not.
This would be the same thing as giving fighters a front quarter invulnerability to "prevent Hoing"
And don't forget, noe bombers do rarely survive at all in AH. Base & town ack will shred you. And if they don't, a single fighter guy will drool about the easy kills.
I'm sure most fighter guys will be much more happy about noe buffs than those at "realistic" 24k
On a final note... I'm quite uncomfortable with the term "abuse".
We often resort to completely different tactics - not only in bombers but also fighters and GV - because the combat environment is a completely different than the real WW2 one. Tactics are the result of circumstances.
On the other hand. and keep in mind im not much of a GVer.
Nothing sucks more when being in a GV fight and having somone up in a bomber at treetop level and carpet bomb the fight.
A good deal of NOE bombers arent going for the perks but for the horde base capture. Most of the time they dont care if they get shot down as it only means they dont have to take the time to fly back home and can come back even sooner with another load.
This is why during base defense I rarely go after buffs at any alt after they have dropped their load. To do so only invites them to come back that much sooner.
