The power info displayed while selecting powers in the loadout window doesn't have the power cost and cooldown info, which means that you have to swap to the powers list and scroll for the power you are looking at every time you want to make an adjustment. It would make more sense to simply use the same power info as the power window, as it's all just as relevant, if not more so, when setting up a loadout.
Yes, please devs. This is one of the most frustrating things in the world when trying to make a loadout.
I had to make a list of all the power with the power costs and cool down time and then made my load out. it would have been a lot easier if that info was on the load out screen
Its a bug they are aware of and are working on Fixing it. Most likely will be fixed in the next version of Revamp.
