Nemesis Draft Changes
Currently, Nemesis Draft has many ass pains. Being able to trade champions is just too convenient. "Oh hey, I'm an Urgot main! Let's trade! Urgot gets fed. Also, one troll on your team can give them Lee Sin and screw over your whole team with no repercussions. I don't know how this would be fixed, maybe perma-bans for the highest K/D or winrate champs?
Dodging is a big issue. This one guy I saw a couple times saying "5th attempt" then "6th attempt" cause people don't like their "shitty" champs so dodge from it. So annoying when people dodge 6 times in a row. Give out bans from Nemesis Draft for that.
