I just wanted to share my experience going through multiple brackets the last couple of months!!!
I hit my peak during the Summer, divine 2 and then i took a long break when i came back it was tough but I still managed to hang around mid Ancient and then i changed my PC mouse etc and all went to hell, i landed in Legend 1!!!
It was the worst experience, your teamates are completely clueless on what to draft or how to itemise during games, you cant even imagine how many times i had Am safe and Dusa or drow Mid(if you suggest something they will get their egos hurt and will start flaming) and this makes it almost impossible to rank up if you are not a Mid player and snowball the game!!
From my previous experience in Archon Crusader Guardian its much easier there as the skill level is super low and you can carry games even from pos 4!!!
At the end i had to resort to my Lycan pick to carry me through that bracket, as soon i hit Ancient again it all became a smooth ride with Enjoyable games and functional teamates!!
Ancient 3 atm!!!
