1 - Easy to pick up, minimal growth potential, usually does not require mechanical skill or much coordination to receive value
2 - Good learning curve, may not require either mechanical skill or coordination
3 - Harder to pick up, requires either a lot of practice or teamwork to properly utilize them
Categories inbetween the numbers indicate uncertainty on where to place them.
This list is my personal opinion and based on trends I have noticed so it does not represent the base as a whole. It is also not in any particular order.
1 - Mercy, Brigitte, Moira, Reinhardt, D.Va, Junkrat, Hanzo
1.5 - Orisa, Bastion, Reaper, Torbjorn, Pharah
2 - Zenyatta, Lucio, Roadhog, Mei, Soldier, McCree, Genji, Symmetra,
2.5 - Zarya, Wrecking Ball (?), Doomfist, Ana
3 - Winston, Sombra, Widowmaker, Tracer
To note, I think Ana is leaning towards 2 rather than 3, and Orisa to 2. I’ve also listed Wrecking Ball as “?” since I’m not entirely sure about him yet, though from what I’ve seen without communication he’s a worse ult battery than Roadhog a lot of the time plus he’s a hitscan.
Also, just because I listed a character in 1, does not mean they are “skill-less.” It’s just that I think that the learning curve is far less and as your go higher it is hard to tell the difference between players sometimes.
