At this point I'm using the gamemode as a practice for dodging
No, you don't have any slight chance to win the gamemode Onslaught until you have a poppy and a support ATLEAST if you are as a 5 team, if you are random then that chance is gone, you need 2 adcs and 3 people to protect them...which is very hard to find playing solo..
well..guess It's a good addition for practicing :-?
