...back to the original point, without debating all of WW2...
I would say "yes" to a Me262 with a bomb load in AH. The players have to spend a lot of perks on them, if they want to do a bomb run, let them. The Me262 does not have a bomb site, and it doesnt carry a huge load (compared to a formation of AH buffs), its hard to hit with a glide bomb at high speeds. The Me262 did see service in that role, albeit limited. I dont think you would see that many players rolling it with bombs, most cant afford it.
The Arado 234 is still the "cheaper" jet bomber, and would still be used in the same #s, as the perks spent are "bomber perks".
In the update, I would have the Fighter-Bomber version as 225 perks, with the fighter version at 200, to represent the fact it was a rarer type.
In any event you would not see a lot of them in the MA.
