Honestly, we just need Purify to also block Draw-In effects, grant you the buff even if you don't dispel something (failsafe against server ticks), basically like how it used to be. We also need some CC immunities. 4sec for Stun after it fades (They can rebalance abilities to help off set this such as Ninja's low potency chain 2sec stun), 3sec Heavy/Bind and 6sec Silence.

I'm just irritated that with Purify up I'll still get dragged into DRK Salted Earth even if it has 1-2sec left on it from just dispelling a Stun.

I've always thought Recuperate needed a charge system as well. Everyone basically gets a free full heal with having full mana and that just makes some fights feel kinda bad. If it got nerfed though, I'd like to see damage across the board go down a smidge too, to compensate. 2 Charges on a 10sec cooldown seems fine (maybe even take 3-5sec off if an Assist/Killing Blow is achieved to encourage kill secures).
