The most recent stat update also goes into making individual healer skills more effective, so healing feels less like a matter of spamming and more like an act of balance. Controllers have also had their power regeneration numbers buffed, so that will help that role produce a bit more of an impact. If you can’t wait to try this out for yourself, the good news is that it’s going live with game update 73 within the next few weeks as developers fine-tune the change. So it won’t be tomorrow, but it will be soon. (Whether or not it will hit in time for our current Choose My Adventure run is another matter altogether.)
