You need people to be playing melee to actually encourage in the first place for that to work. 90% of teams these days are ranged players. They're not going to be backing you up or following your lead. The 3s Purify may as well not exist at all for all the good it does, and that assumes you live long enough to press it as you are lobbed with every single form of CC in the game and then finished off by a NIN LB or MCH LB before you can hit recuperate once. Even if you were to get in effective combat range of the enemies melee abilities are so pathetic and weak that you may as well be swatting the enemy team over the head with a pool noodle.
