The old playstyle of holding the heal button whilst your team does the work is, admittedly, dead. But it’s been replaced by something better, a playstyle of comparative challenge to the other roles.
It’s now engaging, it’ll probably require some mechanical skill, your team mates won’t be there to cover all your mistakes anymore, and your skill is far more likely to affect the potential for a win more than it ever did in OW1.
Common complaints I’ve seen:
-I don’t want to play the weakest role!
It’s not the weakest role at all. That’s still dps, your healing and utility has never had this many opportunities to clutch engagements. You’re more crucial to the team than any singular dps will ever be.
-Mobility heroes will bully me
Mobility heroes have been absolutely GUTTED by nerfs for OW2. Tracer is basically meme tier, Echo got sledgehammer nerfed, Genji remains easily dueled by most of the supports, Reaper lost all his OW1 dps buffs, Doomfist is now mechanically forced to move predictably and rely on a self slowing barrier that doesn’t block any support CC, and Winston/Dva can’t team up anymore.
-I don’t want to play Zen into mega-Sombra!
Well, this one is valid, new Sombra is probably the worst bit about OW2.
But other than Sombra concerns, it’s so much better, so much more engaging, so much more skill orientated, you just have to look past the fear of change, practice, and reject the urge to stagnate with the braindead gameplay that supporting in OW1 became.
