I have been raiding on monk and find that of all the abilities gained in 3.0, chakra stacks seem to be relatively useless, in most fights. I use it for opener and unless its a fight like Ravana, that has a decent amount of down time, i find myself form shifting with no time to built stacks. Also the idea of a TP regain is great but unless you save your stacks till you need it, in a fight that has a long enough pause to build the 5 you wont need the regain anyway since the down time is a natural TP regen. and to work it into a rotation is just a no go the gain in the high potency hit is not offset by losing 5 gcds to build. Anyway, would like to see what others think
