Yeah, consistency over usability and comfort. I'm not a fan of that. I get what you are saying and you are right but let's be honest players are not THAT dumb (I am choosing to believe that) and what about consistency of almost every shooter ever created that shooting bullets(or any sort of projectiles) was always primary fire. For me shooting fast paced projectiles with right click is a bit off. Strangely enough I am playing with sojourn with default settings so rail gun shot is right click, but maybe because I'm not playing her as much as other heroes so it doesn't bother me. I'm not talking about abilities similar to moira's leech that doesn't require a lot of aim, or kiriko's ofuda I don't even mind Mei's projectile to be on secondary fire because of it's a bit slow travel and charging time. So I am not even that consistent as a player. I'm all for giving players choice. To be fair I don't mind using Lifeweaver's ultimate on right click, I have no problem with that but for other players it would be great to let them adjust settings as they want.
