my suggestion here is pretty much to either impliment a similar sustem of obtaining the higher tiers like osrs having to defeat NPCs or to get it by doing one of the lesser-rewarding achievment diaries, while remaining in the store as well. giving multiple methods to obtaining would make sense as without it, it really holds off content from people. And new players aren't always completely clued in on the task shop and its workings, so if they're ready to kill shamans, the idea of having to wait days to get shayzien or pay like $30 for it isn't fair.
