Been awhile since I played and even before I never really got very far into ranked highest I've been is silver, is there anyone that would be willing to catch me up and help me get to being somewhat competitive? Would pay if the service is good of course

Welcome back. There is a bunch of boostera/coaches on here that have ranked fairly high. Also theres a new game mode called TFT that might be of interest. So much has changed with champs id suggest playing norms for a while before jumping back into ranked.

normals is best competitive

ragers, afker, feeders, and warheals, to destruct the rift with off-meta tactics

TFT Is a trash game mode, just watch champion spotlights of the ones you missed
play a good 5-10 normals and you should be caught back up
have fun first and foremost!
