I know this question gets asked alot...
How do I climb? Backstory: Last season I peaked at silver 1 99lp before getting demoted to silver 4. I climbed here with Lulu support during the ardent censer meta, if she was banned I would pick in this order Nami/raka>blitz>lux>bard. I would play mid secondary which I played Liss/Leblanc/Annie/Lux/Ori/Syndra. I had like an 80% win rate on Lulu with 60-100 games played. Also, if you look for this info on op.gg you won't find it bc I got an account transfer. After the loss streak I took a break.
I can't really play support bc Lulu seems so so so weak now, so my go-to is morg>Nami/Raka>Lux>other supports. I simply don't feel like I can make an impact playing supports anymore. I put mid as my primary and support secondary. My mid laners are Anivia>Liss/Leblanc>Akali/Veigar/Lux/Annie. Most of these champs if I get really fed I can carry easily. For the most part tho, since I play Anivia (mostly because it is easier to feed with other champs against champs like zed/yas) I can't carry bc most games end in 20 mins and Anivia deals most dmg late game.
TLDR; I'm a support/mid main and I can't carry my team playing mid and I can't make a big impact on the game playing support as I used to be able to before.
