I agree with the above post actually, altho I am not low60s ;p
Pharah is still perfectly usable in casual and competitive play, depending on the skill level of the obligatory McCree and presence of Zenyatta. The decrease in infrasight and hitscan in the meta, for example, is actually very good for Pharah. I think it's probably not optimal to run PharahMercy but there are a whole bunch of map segments where Rocket Barrage is one of the best wiping/clearing ults on offense, particularly on payload and, like, volskaya maybe idk. She also has good counterpick equity. Once the Zen nerf goes through I think Pharah will be able to hold her own a bit better.
I'm seeing more Mercy, because even though she's hard to play and really right now outclassed by Zenyatta, that Olympic skin is awesome (and I got it \o/). Or maybe it's just because people realised they need res/invuln and know how to play Mercy and don't know how to play Zen.
New map looks incredible and I am so hyped, although scared of it becoming the new 2fort or something. x) Sad for no reverse hybrid, since that would be a lot more fun gameplay imo, especially in ranked (where I feel payload is currently the fairest minding the stupid sudden death shit that they'll be taking out and replacing with the superior time bank, and uh I guess KOTH but at most ranks people can't play KOTH so I just cry inside whenever I see we rolled Lijiang or whatever whereas I love getting it in quick play. This also has to do with leavers, since there are so many rounds in KOTH, even though they're short, people just leave).
