I'm not a good player. I move between bronze and silver, and in norms I'm all over the place. I play support and jungle best.... but I know I'm not good. I feel weird when ppl ask what I main because I'm bad enough that I can pick up most champs and do okay.
Picked up posr-rework Tristana for first time yesterday, went top, and won easily.
Now, when I see ppl in my team telling me they "main" Vayne, Lucian, Lee Sin, Udyr, Mid, Top, etc. etc. I feel like they're clueless.
Tldr: I play support mostly. I don't main support because I haven't developed any great support skills.
