By not rolling everyone back k2 just gave everyone the CLEAR message that bug abuse = OK
We at k2 here love our customers so much that we are going to let every bug abuser keep their illegally gained items from the recent patch. I know that this is going to upset the majority of the players (see this topic ) but we care about our players so much that we will let it slide ! Even if you're lvl 50 with plate +6 you can thank us for your Rof and INs, Your welcome ! Dispite the fact that thousands of players play legitly and strive to get good items by killing hard bosses such as Felankor which require alot of team work and effort, we'll just let anyone be able to get a unique now and not roll them back even though they abused a bug.
Happy Hunting Bug Abuse !
(That's what I'm hearing atleast)
