Yup, someone on the US Skull Throne server has hit 40 already. Congrats! And clearly this involved some serious powerlevelling — scuttlebutt on the forums is that it involved a three man (tank, healer, wizard) team, AE grinding, and the old buggy version of the killing spree bonus that was fixed in one of this week’s patches.
I think it’s a pretty impressive achievement. Yes, it involves ignoring almost all of the content but if you’re just trying to level fast for bragging rights, that isn’t the point. On The Vault, the players claim that they weren’t tag teaming (ie. having multiple people play the character so that they can play 24/7) and there’s no special reason to doubt them. They found an exploit before it was fixed, partly as a result of that it has now been fixed.
One thing that is clear is that although there is an advantage to being higher level in RvR, having low renown rank means that they simply won’t have the PvP-oriented gear to stand up well to lower levels once they reach tier 4. And with just three of them, they won’t be taking many keeps or objectives on their own to earn more renown until more people have caught up.
So I see this as an amusing (and impressive) oddity. Well done, now go actually play the game 🙂
