I do not care about immortal builds. They are boring to play. I just do not want to be defenseless because all my skills are on cooldown. With the elimination of a lot of CDR and the increase to cooldowns, it appears that they do not want us to play defensive skills. They even have several items/affixes that give perks for not using defensive skills.
I just do not understand where they are trying to go with the class. They finally throw us a bone and give us more damage (not cannon level but better) but then they make the glass part of us even thinner.
