Whoever say PI is a "good" CD.
Read the spell.
Spell casting speed.
Aka.. doesn't affect dots, only VT CASTING SPEED.
= it's garbage.
So please tell me why anyone with a brain would choose this over the 2 obviously superior talents in that tier that gives us better dmg overall?
PI should be, increase haste and spellpower, and ofc we need to benefit better from the haste along with other stats aswell, but at least with extra spellpower we'd hit much harder so it would be kind of a burst cooldown.
