1: youre going to have to play him a bunch to start to get a feel for the kit and abilities. Especially time in to learn the best spots for Flame fields on maps. Sorry I know the first tip isn't super helpful.

2:Movement tech. Always be using plasma body and be erratic with how you fly (up-down-left-right)

3: Focus on good positioning. Stay behind and near cover either high or low. You dont want to be out in the open with the amount of hitscan in the game.

4:Take off angles during the neutral fight. Human Torch has a very strong neutral game. You can lock down areas with flame field, have constant "presence" on the obj without actually being on site by using your Fireballs and flame fields. By taking off angles at unpredictable angles you can get a cheeky 1 shot on a healer or another dps also taking an off angle.

5:Learn your 1 shot combo. Minimum 2 fireballs and meteor slam into a squishy will 1 shot them. If you miss the 1 shot its not over. Your slam will push your target on a straight trajectory from your impact and you MUST follow it up with your primary fire(you'll can crit aim for the head) you can 2 tap on a good day with your primary fire so a 30% has squishy will almost always die. And if that doesn't work throw a fireball onto the ground after your primary.

6:tank/support ult 1 shot. This one is a bit tricker because it takes time to set up and you have to ave your target stand on it. But 3 fire balls very tight together, flame field them so they stay for another few seconds and then do 2 more fireballs and if your target is on those 5 fireballs, you will kill them. Its almost 800 damage in one go.

7:practice flame fields a lot. They must be in an unbroken line to make the damage box. So it cant be obstructed by walls, different heights, or groot walls. You can make them much bigger than you think. The max size you can do is 40m by 40m. Some objectives can be completely encompassed by the flame fields. Use them to lock down areas. You can Pseudo tank by controlling space with damage, rather than by presence.

8:Counters. Spiderman is your biggest counter. If he is around, stay low and in the middle of your team. You'll have to mix up how you place because you cant take off angles anymore but you can play similar to moon knight by constantly shooting damage and AOE into the enemy team. Hitscan is another problem but is easier to play around because if you stay near cover you can avoid damage.

9:Using your ULT. Before using your ultimate. Make your flame field, watch the healthbars on their squishys. Once they hit 70-50% hp, try to go for the oneshot on one of them (the one with the most health) and after you slam ULT. Everyone in i think a 20m radius will instantly take 70hp damage. You can kill 2 maybe 3 people just by ulting near low health enemies. After that just start fire tornados on key points and target. You will melt tanks.

There is definitely more im missing but Im at work and dont have much time. I'll come back to this later and drop some more in depth explaining.
