I've currently tinkered with Pelting Strikes a bit further:
To make the mods of this CA more consistent and meaningful in choice, at least in my opinion, I've put the chance for critical hits onto the silver mod and opposed it with a likewise chance for sure hits.
The debuff of enemy phys armor I've put onto the gold mod and opposed that with the debuff of enemy defense values (EVW).
For this, the cooldown regen of the spell had to go, as I always felt that the cooldown regen on any attack skill is rather a placeholder.
I'd rather change the cooldown regen on the Battle Stance, so that if you skilled BS as a buff, it would regen the cooldown of all Exalted Warrior aspects and not only BS.
I have been thinking about an actual cooldown regen for literally all hero CAs, as this would synergise nicely with its 'Idol' mod, but that's prob rather impossible to balance, I guess.
