Event Reward Requirements [Upon Winning a Match]
I think that having the requirement of winning x amount of matches really made the gamemode of the Bilgewater Event quite toxic, due to having wins be the main thing in receiving the icons. I gave up on trying to get the 3rd tier TF and Graves icon due to the fact that nearly every match I faced a diamond player (meanwhile, I'm gold) and made it near impossible to get the icon. I made it really close, but the matchmaking in that gamemode felt terrible and I don't think "upon win" should be implemented in anything aside from IP/XP Boosts or First Win of the Day. This isn't meant to be bashing on the gamemode, but for the next event planned, please try to not implement "On winning a match, you come slightly closer to receiving the prize." I know that we had plenty of time for the event, which I did appreciate, but the requirements were just overboard. In all honesty, you could have made it "Upon playing the mode with a new item, you gain a point," and just increase the amount of games needed to be played.
TLDR; (Most) Events that have an "upon win" counting towards rewards shouldn't exist, and should be replaced by "playing a game."
