It’s not a great comparison though. Genji only gets picked for his ult. Saying “his playstyle’s good but his ult is too strong” doesn’t really make sense. Of course his regular play isn’t as good, he makes up for it with probably strongest offense ult in the game.
Doom is also a bit different. Even I can consistently catch someone with e, uppercut and throw two shots into the simple trajectory. If I had high ground before the dive I can rocket punch out. I’ve frequently got 3k with him and still left if I have ult up and land a good RP. When I started learning him he dominated my highlights reel lol.
By contrast I have done a proper one clip on a moving target once in maybe 10 hours of playing Tracer. The consistency I can get a pick with Doom is much much higher than Tracer, and even if I die in the process as long as they don’t have a Mercy we probably win that next fight since losing a support ult is so huge in OW.
Pro players don’t even consistently get one clips against pro players. Next time you fight a Tracer count how many times you get legitimately one clipped in a game. If you don’t get one clipped the Tracer can’t recall out back to their previous position and is pretty all in at that point. And if they’re not good enough to one clip you it becomes very easy to survive with any healer support. Even in games where I have 40% accuracy on her and didn’t focus tanks I often can’t punch through a single dart or a healing orb being on them whole time (which will be 60 seconds of healing per clip). Against repair pack there’s no chance for a mediocre player like me. By contrast I was getting extremely fast TTK picks on Doom within 2 hours.
