In current state, a drawback was taken and made into personal mini-murderous prowess.
Half of the roster of LZM have it. Make it trigger at 25% or just nerf the effect, it is just insanely good.
You were worried about +1 attack buffs on sisters of slaughter? How about if all lizardmen mid and top infantry, cavalry and monsters receive 10 attack, +15% charge and ph res 5% after they get down to 50%hp? Especially spear or halberd infantry getting that insane attack buff.
Please explain me how is that ok?
