Have weapon skins that can be purchased in the store. Maybe they won't be as unique as the weekly skins, so there is still an incentive to do the weekly challenges.

Skins that you can buy with tokens that have special effects like particle effects or luminosity.

Weapon skins in the shop will be amazing addition to the shop it will follow the same star tier system. 1 star mostly just basic colors. 2 star simple designs like a checker board skin. 3 star designs be glowy texture and great designs. 4 star skins will have a simple animation like a galaxy. 5 star skins will have a contrail or a special elimination animation like a christmas grenade launcher that will freeze the enemy and shatter or a easter one witch will shoot eggs. I really hope this gets added that would be awesome addition and will show more people their own styles and taste. Btw the picture i added is a quick concept of the animated galaxy grenade launcher.

I think there should be some weapon skins in the shop

It would be really nice if we could buy exclusive/very old weapon skins with real life money. It would still keep the weekly gooing as the weapons in the weekly are new but the ones that will be exclusive or where introduced in a weekly only 1 or 2 times a long time ago (Eg ghost bow) could be purchased with real life money and the price depends on rarity or somthing like that.

Now that we can buy tokens it might be time to sell weapon skins. It will devalue weekly rewards a bit but it would be cool if you could get the skins you missed but always wanted via tokens. Maybe just price them kinda high so doing weeklies is still valuable and the skins maintain some rarity.
