"Meta powers", IMO, (ones which basically benefit all other powers), tend to be problematic. The fact that hasten improves the recharge of *all* powers makes it exceedingly powerful. Make hasten a toggle that costs a certain amount of end/sec and reduce the recharge bonus, to put it in line with the leadership powers. Alternatively, what if taking hasten allowed you to "tag" 3 other powers, who would have their recharges affected, instead of it being a huge global bonus.
