So i really like this game and i'd love to go competitive on it, i know the basics some advance, i get my own builds (not recommended) and some other stuff.

Now what worries me is my ELO, ive heard the lower your queue time, the lower your elo, and my queue times are pretty short 40 seconds or 1 minute, once i got to 9-10 minutes, but after some solo queues with feeders and leavers (8 or 9 i think) i think my ELO dropped to the abyss.

Now i think the solution would be only goig pre-mades if the solo queueing is screwing my ELO. Any tips on high level play? im a good tank and average-good with mages (no carries i have a hard time with them).
