There is still the same problem with the pvp ban & the Arena of Honor. People can exploit the game's lagging command to prevent the player from joining the game (button still shows for 1 second) just like the situation with the Arena of Honor.

I know someone in particular (on their many accounts) abuses this bug at an incredibly high amount. I saw a situation where someone rejoins every time I'm about to kill them and constantly keeps killing me in which I cannot rejoin. I think this rejoining ban elixr should be removed since that STS can't seem to fix this problem.
