Well, it's only cosmetic so it's not like it has any affect on the game world whatsoever (other than "bragging rights"). That being said, EA & Mythic are pretty big on giving away in-game perks for out-of-game activities and purchases.

Whatever it takes to keep your current subscribers happy, and maybe recruit a few more along the way.

If that's enough that you would never try the game then you are either a pretty weak troll or were never going to try it in the first place.

Incentives to actually test on test servers are sadly needed pretty bad. most people treat test servers as the place to find an ultimate build or get that two hour jump on the latest techniques for the current FotM class...so they decided to give people a reason to actually test on their test server...which will result in a more polished, complete and balanced class as opposed to fixing it all in the next couple of patches because it didn't get enough testing.

Of course, if that was the case, you'd be complaining about that instead.
