I agree. Some people where banned for a reason while some others for no reason at all.
I believe those banned for a reason should not come back. That's why they were banned to begin with.
Imagine on the very last day of vmk a flood of formerly banned characters entering the game. Not only will they add lag to the already heavily occupied server but also their questionable feelings about the game (after all the time being banned) will bring about tension and if things get out of hand, who knows what will happen.
I don't want to see the game being shut earlier than planned, then again if possible not at all, but that's another thing.
