I'm afraid there is on techinal issue with this solution though: How does the system track that you've actually obtained certain gear at somepoint? The way the Calamatiy Salvager knows atm is by checking of you've got the achievement thats tied to the gear - thats why you can ONLY buy the Garo-gear when you've got the achievment tied to that gear-set. To buy event-gear you're never required to have obtained all the gear from that event during the actual event - as long as you get the achievement, everything will be unlocked. So unless you want to have achievments for every single piece of gear (or even for every gear-set) this solution cant work under the current system.
