Figure this may be useful since it's a 6-stack scenario. Matches listed were played consecutively with the first being relatively well balanced, and the two following being absolute stomps. In both of the stomps, my team was losing by about the 6 minute mark.
I'd say the experience level of my team is a pretty wide mix between somewhat regular player and very occasional matches, but most of us run a build from the build menu (that is to say there is very little intentional counter-play for 4 of the 6 of us, like buying knockdown for example). One of the matches, an ally was playing McGinnis for the first time and was lane matched against an experienced Vindicta who held the souls lead from 3 minutes onward.
