I still haven't touched ranked, but I probably should this weekend. I'm having a similar mental block as I did doing ranked in Splatoon, where I constantly hesitate to play before I feel like I have a proper "main" setup laid out that I feel confident with. But, being generally crap at games as I am, I never do well enough with anything at all to reach that personal threshold. The end result is a bunch of different ideas and weird little experiments that don't work and never enough time dedicated to any single thing to gain proficiency.
Even now just trying to pick out like two mains, I'm having an impossible time whittling it down from like 5 options because I can't reconcile what I'd theoretically like to use vs. what actually seems to get better results.
