ya but the only reason Anet did it is because they thought it’ll boost Mini sales.
Take for example, gathering tools, most people already bought 1 or more gathering tools, I doubt some flashy mining animation will boost people to buy more than 1(at least most people wont’).
I think something like instruments, or maybe dance could boost sales if they make it account bound. But not necessary everything. You have to remember ANet is in it for the money. So somethings are better of not account bound so people’ll buy more than 1.
