META means Most Effective Tactic Available, it doesn't mean it's the only way you can win. Sure AP Lee Sin support is troll but things like Nautilus and Brand support, or marksmen junglers, Rammus top may actually be decent, win you the game and eventually become meta. So please if you have an off meta pick, give the game your all and if it ends up being complete garbage then let them know it isn't good by saying it just doesn't seem to work.
I get this a lot when I go Taric jungle. Sure, there's better options but its not completely incapable of working out.
When other people go off meta stuff I usually say "I'm not so sure that will work" or "Bold move. Have you done this before?" It usually means "I advise you do something else" which I think is nicer than yelling out troll build, report this player ff@20 like so many other children who play this game seem to do.
I like ad Diana but I haven't played her after s6 her ap is just to good
