This is very true, I have an account where i only play tank and I only play within a particular timeframe each day. I have a 30-5 WL just by the fact tanks are strong atm and playing at the right time helps avoid large swaths of throwers ect. However i will say the only reason I lost 4 of the 5 games is due to leavers and/throwers. It obviously is not discouraged enough and I believe Console accounts should face harsher penalties due to the easy creation of free smurfs.
