I would like this thread to be positive, as I don't have knowledge of all dps classes and how well it benefits each one, or tanks either really but this card has it's uses.

for starters, whenever you use it on yourself depending on if it's enhanced or not, it immediately starts work on your draw/spread CD, on top of being able to pop any cooldowns of your choice. i like that i can use it and get my next card faster.
