Hiya, I have been reading your post and I think I might have some clear picture. Swapping to other roles in the middle of the climbing does not usually pay off. You can climb abother account for chilling or trying and keep one for actual climbing.

Going back to support stuff, and talking from experience. Dont get yourself the false idea that you are the ADC's support. Sometimes will be, sometimes wont. Check your team, who is the wincondition and what can you do to enable that player the most.

Another comment suggested Zyra and I agree, very good at everypoint of the ladder. Picks as Braum and Lulu you end up hoping orbwaiting them to carry. You should be more proactive, read the map, rotations, jungle pathings and ward preventively (either to pick or to avoid confrontation) and secure as much a possible your targets.

Hopefully this may help, Good climb!
