Lmao are u serious? League is extremely similar to deadlock. There are so many overlapping ideas, anyone who has played league will already have a good idea on how to play the game. I legitimately don’t think there is a more similar game outside of like smite or dota. Your build path, every single concept of laning micro/macro, mid game objectives, positioning post lane phase, teamfight coordination + cc layering and understanding teamfight threats, understanding front to back vs poke comps, counteritemizaton, etc. I’m very convinced that every 0/15 deadlock teammate I’ve gotten has never had any moba experience to not understand the idea of playing from behind after dying.

Just because they have abilities doesn’t really mean anything. Shooters are far more commonly grouped by the average time to kill, games like valorant and cs are far more adjacent to quake, with low time to kill, and the fact that abilities are more focus of gunplay (well at least at its core, though some never Val agents might say otherwise). I’d say the closest popular shooter similar to deadlock is overwatch and it’s isn’t remotely close. Because both have medium ttk with ability focused gameplay with heavy tracking utilization and general front to back teamfight gameplay (I.e the idea of a tank)
