I don't think, that the game needs a speed up by small recharge increase and nerf hasten a bit.
Thats like: nerf AIM a bit and increase the basic accuracy because everybody skills AIM (if he have it in their power set).
Thats not good for the game. You have to be spoilt for choice! Quality instead of quantity. Be aware of the 24 powers you can choose and choose it wisely for your gameplay. Thats it.
I know you want it to slot other powers and choose other powers to make the game and your choices more easier, but this will not help the game. There are still so many things implemented to make the gaming easier, but... sorry for the hard words: this is the wrong way.
