ok, i need some help with how the game has changed since i put it down like 4 years ago. it looks like the top tier planes have been nerfed in that they seem to fly like bricks now. i get that this was to level the field for newer players, which i'm fine with, but which tier is optimal for power and maneuverability? (WWI) also, i never maxed out my bomb loads because more bombs meant worse maneuverability. now it seems like all the kids are taking 3 bombs and they can still turn? are there any other changes to essentials that i should know about?
