Realistically, the undead racial will do similar damage to the goblin rocket, and be on a 1-2 minute ICD.
You think so? It would make sense if the internal cooldown was longer, but if racials are being reworked, who knows at this point I guess.
because you cannot WotF offensively or defensively.
because you cant use stoneform to clear diseases or poisons (aka crip and infected wounds)
Orcs sit in stuns for less time.
Also goblins lack resistances which is pretty big.
My god open your eyes...
