Normally, the approach to find an interview for the Colosseum is relatively simple, but filled with some frustrating challenges. I check the SK Arena Rating tools, and scan the highest rated teams for that week. I need to keep a special eye out for which teams are predominately clustered on one server. I try to rotate servers each week, so that we're getting decent representation across the player group. (We're trying, anyway. With a single interview each week, it'll take a long time to get someone from each server.)
I then create a Death Knight, kill a few dudes for some mailing cash, and haul my happy kiester off to the nearest mailbox. I then mail almost every person on that server who is in the Top 100. (I encourage them to reply to my WoW.com address, so that there's no risk of confusing me for a scam.) I regularly max out the allowable number of in-game mails a character can send. For every 35 to 50 in-game mails I send, I usually hear back from one person.
However, while canvassing the server Korgath the other week, I was happy to see many more than one person responded. This was exciting news, because it meant we could do something a little different. I fired all of these excellent Arena players the usual questions, with hopes that we could feature all of them in one shot. I wasn't disappointed, and I hope you won't be either.
