Not a big fan of the tribe, what with them being one of the major threats in the game, but I do rather hope devs didn't intervene themselves to balance the game out. If you want to push for a certain PvP dynamic, do so via carefully balanced mechanics, not magic powers. If it was indeed a case of a dev's totally separate in-game character pulling this off without magic powaz, then that's as legit as it could ever get.
Don't really expect much to change about the situation based on either people's protests or approval of the events, but I'm just saying what my stance is. Said it right from the start, don't care who the new devs were/are as long as they don't favour any one faction.
All that being said, I've no clue what actually happened, so I can only hope legit stuff went down, because if that's not the case then that sets a pretty bad precedent for the future lol.
