I give up on black market brawlers
It takes too long to get the t3 icon, 15 t3 upgrades is insane, most games are a stomp because the match making is poor for this mode, and a 20 minute game is too short to get a t3 upgrade, Thus I estimate it will take at least 30 games to get with half them at minimum needing to be 30 minutes long to even get a single brawler upgraded to rank 3 on anything.
For those keeping track thats over 10 hours playing a game mode that isn;t that fun, isn't ranked, has poor match making, and all to get an icon that isn't even that good.
I don't care anymore. Riot, please consider how people actually play next time you set event goals so that its something we can accomplish without wasting tons of time.
