What Skills/Trai should be Removed, Adjusted, or Added for the new 4.0 Battle System?

Afraid to say that turrets do not fire while under promotion as such they do have a dps loss during it (by how much I'll let a MCH main fill that one)

No, they lose the auto attack under Promotion, MCH doesn't take any % loss having the turret out at all. Even with Gauss Barrel, if a MCH has the turret out they gain back their auto attack.

I m wondering any time, where this misinformation actually come from. Its definitely not true.

Both turrets will not doing ANY damage when they are in their mana-/tp-regeneration-mode. That means you re losing about 13-15% of your DPS while recovering mana for other people.

EDIT:
While the auto does make a % yes, promotion doesn't weaken any weaponskill damage output, which is what I should have stated, so that's my fault, regardless though BRD losses the auto and also gets hit with a 10% reduction of damage across the board for Ballad and Paeon. So if we were to math using 13-15% auto loss on MCH, a BRD losses 23-25% for the same skill. A MCH still gets to keep their auto with GB on by just using the standard Rook, so even in that case a MCH potentially nets 45% more damage using GB which is the same skill as WM.
