I'll say it as I said it on CB : Attune need more interactions outside the T1/T2. Tying the set's mechanic to two incredibly low impact abilities around Attune which is janky in itself to reapply in moment to moment game play feels terrible. I know you want people to have a reason to take the T1/T2, but guess what? It's okay to have powers in a set that aren't taken. Skips are fine. I, as a matter a fact as a player, don't find it exciting to take abysmal damage abilities that do very little without Attune for my damage. Earsplitter and Sandman's Whisper should enhance Attune and I don't know why they don't.
