Yes, bombing runs have been slightly increased, but since all units health has also increased, they cannot take out heavy units (ATAT, T4B, M2 and T2B take heavy damage and so on) and buildings (turrets, production facilities) with one pass. Mind that bombing run range has decreased as well.
As for MP, i hope that when both players have the exact same mod installed, then they can play with it online. If not, Torpid told me that they're working towards this mod-support in coming patches (if not compatible already). I really want to play the LAN campaign with my brother too, but with EaW:TR installed, not the original game
Btw, im posting a new thread about the upcoming EaW:TR version 2.0 . Major changes.......stay tuned
