You said SR’s problem was mid-game performance. I said ok let’s just say I believe you. Now, to fix your problem, do something that will boost its mid-game performance BUT NOT its endgame performance (because everyone here knows SR is strong enough endgame). The only change that could possibly relieve your mid-game problem, while also NOT buffing a top tier endgame powerset, is reordering the powers. You don’t get to say only the mid-game is the problem so let’s buff the already-overpowered endgame. So all of your other proposals can be immediately ruled out for not being appropriately targeted at the only actual problem area.
