Thanks for the info guys, guess i'll just take the plunge then

Hi,
I haven't played properly in years and my global rating is still at 1100.
I'm worried of joining games and this kept me from playing online for a long time now, because i neither want to ruin anyones games, since i would doubt even being something like 700 these days and i don't want to boost anyone either. Is there a possibility for resetting my global rating? 1v1s i don't care about, the only one my shittiness will hurt there will be myself.
Greetings
