A better way to ban
If you spend any amount of rime on these boards, you will see plenty if people begging for their accounts back. Whether they admit they deserve a perma ban or not, they all want another chance. So, you get them back on a new account any way, nothing solved nothing changed.
Why not make a game mode for problem players? Another rift, where anything goes. You tilted and raging...go play on the other rift and take out your frustrations on other flamers and feeders.
A game or two where problem players can get things out of their system should help keep the real rift a calmer more peaceful place.
And, instead of perma bans that either frustrate and alienate players, you send them to the other rift for some reform time. I can't imagine anything making you want to play a nice friendly match more then 2 weeks stuck in rift hell with every other frustrated tilted feeding obnoxious annoying player.
