Too easy to snowball, impossible to come win if you fall behind.
I have yet to play a match this season where the that fell behind came back and won (with the exception of AFKs and other non-gameplay influences). Seriously, between the broken champions and the OP mastery keystone Warlord's bloodlust and the new mechanics in vision, turret, minion, and items, there is little possibility to win from a comeback if the winning team isn't throwing (basically they don't have to change anything in their playstyle and can play passively since waves push for them by themselves if left unattended). Blue side has an advantage over red since Rift Harold's opening facing them.
If in solo que, a Tryndamere, Yasuo, MF, and/or a few others that appear in every game get fed early on, or take tower first, you basically lost (unless in a party or all other roles on your team are fed heavily)
Yeah I know it still is early in the pre-season and this is just another qq post to anyone who mains these champions. But come on.
