Why is dark soul undispelable? considering locks will have Two dark souls next patch, while mages only One 3 min CD icy veins is dispelable? Both spells should be dispelable. I wouldn't mind Dark Soul being undispelable if it had one charge, but two charges?
It's like buffing a Ferrari (Dark Soul) making it unstoppable, but nerfing a Ford (Icy Veins). Everyone knows which is scarier.
You cant compare the offensive CDs of two classes that work completely differently like that. If you want to compare dark soul to icy veins, where is warlock equivalent of deep freeze + orb?
Mage "equivalent" of dark soul is deep freeze + blanket silence (maybe with an orb) and its on a 30 second/1 min cooldown.
All warlocks specs (except maybe affliction) are incredibly dependant on darksoul for landing kills. Mages do not need icy veins at all to land a kill.
