Account Hacked, One Question.

Alright so my account got hacked (this is not the account), but thats not exactly what I'm trying to address here.

I know things such as gear and gold can possibly get atleast mostly returned, but I'm more concerned about my arena team. I am sitting comfortable at rank 3 on my battlegroup and likely getting gladiator, but if the hacker leaves the arena team on my character, would it be possible to have my PR on the team restored?

If my Personal Rating on the team can't be restored when I get the character back, then I have basically wasted the last 5 months of game time since all I do is arena.

TLDR; Can Personal Arena Rating be restored if my hacker leaves my arena team.

Edit: Character in my signature is the character im concerned about.
