Looking for High Elo Support to teach me how to climb as a support.

Support main here, don't main support in ranked. Learn another role.

unless you're really committed to playing like 500 games as support to climb up to a higher elo in one season, don't play support. You must be extremely committed to playing support, and my best advice would be to just learn decision making, objective control, and map awareness/vision control first before strictly playing support. Without the fundamental knowledge of those ideas, you won't be able to climb as a support because on top of all of that you also have to have experience with the champions you play, know when you can get away with certain things, how to play behind, be able to consistently land skill shots, and most important of all, be consistent with whatever support champion you main. I climbed from bronze to plat in one season, but it took me 300-400 games with thresh alone (i'm a good thresh main), and even then like I had a like 52% w/l ratio on him because you can't always carry when your solo laners or jg just do really badly, or when you're having a bad day and can't land skillshots or peel correctly.

Last season I had over 700 games as thresh or something.

what rank did you end at?

also add me on league so we can talk; ign is the same on here
