Alright, with the newest update going for the removal of QC(which I don't really care that much as long as they make the kinetic system better) we've got yet another gameplay affecting item coming to the shop. On one hand, they're going to remove one way of infi farms but on the other a lot of folks who have enough money to spend can just buy a ton of all that stuff in anyway. Which is a lovely pay-to-win dillema. I get that there's a need for funds that they need for running servers etc., But there is a lot of stuff that the community has been asking for, for a looong while now, that could be added.
Instead of having a ton of gameplay items ready to buy in shops they could easily go for the cosmetics, with so many options, give people more customisation of things like UI and sound effects. And all of these things are client sided too, so none of it would add more stress on the server side of things.
From previous versions themes, sound effects to choosing different colors to specific UI aspects, XM colors, portals, fields, links, different map layout themes, so forth. The amount of individual items and packs they could make with this could be fairly big. And I'm pretty certain a lot of people would go into that fulheartedly.
