Destro winrate being better is totally logic, normal and intended => all those cities with 8 engis+5wh+6SW+ random dont go nowhere...there are plenty of order instances like this..
Have said SEVERAL times => destro being overpopulated means that:
-CITY: You need to form full wb to get pop: even with 24 man i have missed cities if queued after the firsts 15 mins
-CITY: mostly soloq dont get pop
-SC: soloq last loooonger, if you are a solo dps youre really fcked...
So having a harder access to instanced content foced desro player to:
-Team up: to maximice the chances to pop in city and reduce wait times for SC
-Good comps: maximice the chances to win => when you miss too much cities for overpop you need to win when you are lucky to get a pop. same for SCs...you cant wait 30 mins for a pop to lose
is not that hard to understand...
