+10% more damage is enough to wipe whole squads with full HP.
Terror mortar needs t4 to get bonus damage, so why AB mortar has BONUS DAMAGE and FIRE UP at the same time without t4 upgrades? I think the damage should be taken off of this thing, since fireup and paradrop(?) is enough for this thing.
Bonus damage can be part of "prepared postions" t4, but I don't think that's a good idea anyway.
Posting it in general discussion, since certain someone banned me from balance.
