A lot of high elo players have given a semi working tier list for which heroes to use to climb and as a player here I can disagree with some picks… And I’ll do it for every category. Here a big deal is that counters matter much less.
I’ll use several ratings and explain what they mean
A - always good to play for most maps and situations
B - good in a lot of situations to pick up
C - You need to know what you are doing with the hero to make it work. It will not be easy.
D - 90% of the games it won’t work. Don’t bother picking them. Even if you are very good at the hero… You are better off slending effort in playing another.
A tier
Reinhardt - Rein is a bread and butter hero in most comps. He does well as most tanks. He has a decent skill floor but you can pick him up with some skill and have a good chance at winning most games.
Sigma - A controversial pick I know. Lower elo ttk is generally lower and you are less likely to get punished for mistakes. At worst you need to practice ulting. His damage isn’t too difficult to use. Even if you are not the best at using your rock at proper times he is a decent tank.
Zarya - People shoot your bubbles. Your ult timing is very important though. A lot of Zaryas underutilize it. Your charge is easy to farm.
Mccree - Mccree is probably the best dps to pick up. He can easily kill people, can put down pressure with his poke, his flashbang is broken. He is very reliable woth honestly low skill floor. High noon is actually useable sometimes.
Hanzo - Mr. Handsoap is incredible. He is incredibly bloated as a kit. His weaknesses are easily offset.
Mercy - While it’s a fact mercy can’t carry she is incredibly reliable and she is way less likely to be focused. As long as you don’t die and you benefit from a overall lower ttk and consistent heal output. You can pull of a lot riskier rezzes
Ana - she is honestly crazy consistent and your positioning won’t be punished as hard. You don’t need to hit crazy shots or insane nades, but if you do you can carry. Even sleeping a healing hog is great.
B tier
Roadhog
If you can hit a hook you can do a lot. You will rarely die if you manage your cds. Still an ult sponge.
Orisa - People can’t quite run you over and your recent buffs combined with your buffs make you amazing. Lacking rock and sigma ult make her a slightly worse sigma in low elo where her benefits don’t shine as well.
Echo
Echo is great if you can play her well, but she isn’t that consistent at lower skill levels.
Junkrat
For low elo this is probably the best dps ult. People struggle at playing against you and you can pump damage into chokes. Not as versatile.
Ashe - Honestly dynamite and bob make her a great pick but she’s not as good as mccree currently
Torbjorn - in my opinion underrated as his hitbox issues are not as big, and his turret and primary are very consistent in applying pressure. Great ult
Baptiste - a harder to use support but he has a lot of value with both damage and heals and sustain. A jack of all trades of support.
Tracer - a low elo tracer may not be the queen of high elims but she is great at backline disruption.
Pharah - Your counters are vastly weaker here. With a mercy you can dominate games
Lucio - your healing aura and good amp timing is honestly enough to pull your weight. You can stall well and in maps your boop may be invaluable.
Soldier - He is reliable, not too difficult but overall meh.
Moira - She is fine. You can genuinely get away with diving solo supports it immobile weaker dps because of how bad peel is. Your healing does the job and you are likely never going to get stunned out of your ult.
Mei - She is much much better in lower elo. Her ultimate can get a lot of value as well as clutch walls.
C tier -
(Technically C+) Genji - now this is controversial but most genji players either completely fail their blades, or have decent blades but are much worse at picking up kills. Generally very few genji mains have been a threat.
Doomfist - You need to be able to pull off doomfist to have value.
Widow - You can be B tier if you can apply enough pressure and can aim well with Widowmaker you can pull her off. She like the ither tier needs you to main the hero
Symmetra - People have gotten used to symmetra as one of those heroes some people think is free. I could move her to B if it was half a year ago, but her place in the meta and nerfs hold her back. She can carry if you know how to use her well
Dva - Dva is just weak. People don’t manage matrix well and don’t use rockets well or her shotgun engage well. Dva players most of the time have low kill pressure on players mostly because of lack of skill. A good dva can shred people, but it’s hard to pull it off
Winston - People have a very hard time playing around winston as a main tank, and you are more likely than not playing into bad matchups for you. Rein and mccree are a common sight. You need to be good.
Zenyatta - Your orb if discord has very low value unlike high elo where its broken. People just are bad at focus fire. You have no self peel and its unlikely anyone will peel for you. You need to be good at killing dps 1v1.
Brig - People can’t play around her well to enable her. You may be left to die often. People don’t stay close to you.
D tier
Wrecking Ball - You will feed. You are not good enough. Even if you are people can’t follow you up… But let’s be real you are gold or lower it’s not worth learning him. Yes even without the nerfs he just isn’t good for anything but stalling at that skill level. Yes he is broken in high elo.
Reaper - after the nerfs its not worth it. He is just bad.
Bastion - He is slightly less bad in low elo.
Sombra - People cannot play around you. You likely cant flawlessly track to the point if getting kills… And even if you could just go tracer or soldier or symmetra
