Let me start by saying that shard shop is really awesome and I'm glad we got that initial rework that brought all the gear in. However I strongly believe that we need a small modification to it!
Shard shop has very few slots and too much gear and the problem is that some times days can pass without certain pieces rotating. I know this may be the intention to cause players to buy refreshes however those refreshes can be expensive and honestly spending crystals just to make 5 salvages appear doesn't make alot of sense.
I recommend that we expand the store to have more slots and instead of 10 pieces rotating in one slot, to have a maximum of 2- 3 pieces rotating at each slot.
This is literally the easiest implementation and it's not to much to ask, makes carbanti- guns- cuffs rotate on the same slot, all gold pieces have their own slot, gear 12 salvages have a separate slot from rancor raid gear, ect.
I think that's very useful QoL and it's not going to affect revenue much.
