Outland store and progression tiers
I clearly understand that a coin shop will be a thing on Outland for financial reasons, but at least please consider making the buyable gear restricted to the current content -1 tier, for example if Tier4 is the progression, then make the shop loot to only consist of RHC gear and maybe the lower cost BOJ items, and so on. Also when progression reaches the T6 tier, don't let the T6 tier items (And the legendaries of course) to be buyable.
People can buy gear as a catchup mechanic, there won't be a gazillion rogue/warrior running around with Coinblades of Azzinoth / Thori'dal; it is a win for everyone on the long run.
