u do have to keep in mind tho we didn't get assigned roles before the new champ select, and in the old one people would all declare which lanes they could play and which they couldn't, so more often people who picked earlier pick their roles that didn't clash with those coming after. i cannot play jungle at all and it bores me to death so i avoid it nonstop. and because i let people know my issue with it, it was incredibly rare that people would leave me with that role.
however since people have their roles assigned to them now they're a lot less interested in giving that role up, in all the times i've been auto-filled i don't think ive yet to have someone say yes when i asked if i could swap to a different role, so its actually far more likely ill get a role i cant play now than with the old champ select.
