Ayiza has some wacky ideas about PvP. I don't understand why he keeps trying to allow restricted PvP builds to bypass quests to obtain PK gear they normally wouldn't be able to get due to quest xp. First they tried with the duel arena rewards and then again with the restricted account builds that would null quest xp. Both times the community struck it down.
I didn't actually design Official Account Builds nor the PvP Arena rewards, just that by nature of working in Community Management we provide support on all updates.
PvP isn't something everyone picks up for various different reasons, so you'll often see myself (and now Mod Goblin) being the CM names behind those projects.
I do however think there's a huge amount of potential to be had with Official Account Builds, but the main benefit was never to allow players to bypass quests. I think most of the higher tier gear is still hard-locked behind level requirements and those that weren't would have been considered during Community Consultation.
