I am playing a melee class atm. There are some abilities like Blood for Blood that sound amazing if they were not on the global cool down. I don't know how many times i have jumped into a group of enemies to activate this ability and that 1 second animation you have to go threw just means i die from 50 things hitting me. I think a lot of the skills and abilities could be taken off the global cool down. Potions included in this.
