General DiscussionJust a MMR climb question

Well guys i am back into the game for like 2 weeks...I used to be around 4,7-5k mmr before my quit (a year and half nearly). My brother and some other friends used to play some games and i found the acc at 3k mmr. I clearly understand and feel that i am not a 5kmmr at the moment missing many mechanics ingame and reactions i used to have. BUT at the moment i lay around 2,6k !!! and thats clearly not my mmr. With people dual miding picking Am for offlane or dual farming safe.Things that i ve never saw before.Is there a chance and a way moving out of this toxicity? Or should i just pratice here and create a new account to get the calibrated MMR. I d love to know if anyone has an idea to offer about climbing from here. For me it seems impossible.Lost games while i had 3-4 levels diff or 300-400 gpm diff on early-mid game from the 2nd player on the graphs...
