I don't see how balthizar faction would stop this title from being bought...
oh noez,, faction is buyable.
Z-Keys were intended as pvp rewards, and are gotten from pvp easiest. I'd say this title counts due to it being related to pvp. Someone spend the time pvping to get them, just because they sold them to a pve'r shouldn't mean anything. If all the 'hardcore (lol)' pvp'rs we see on these forums stopped selling their keys, maybe people wouldn;t get the title so fast. Yes you can get them from pve Z quests, but common, the pvp ZQ is the quickest one of those quests.
For those sayiung it's to easy to get the title, are you telling me r6 hero, r3 glad/command/codex are hard, like at all? You call yourself a serious pvp'r and think those are hard to get, lolz. Sure it takes a little more time, but you complain about having to grid a pve title anyway.
I'm not saying the title was implemented in the best way, and yes, I think customized keys would have helped, but common, getting 1 pvp title that isn't Zaishen isn't hard either.
Stop QQ just because someone can get a title you have...
