Instead of VP just being a bar you fill for rewards I would personally love a rotating shop where you spend them. you could still keep pvp rewards but use the point system for the shop. here's an example (things for sale and cost are purely arbitrary and used for example purposes).
-1 teeth for 5 points each (max of 50)
- 1 gear for 5 points (max of 50)
Could also be a great way for f2ps to get promo units, or to reintroduce promos after their release. for example:
x1 mech trooper - 500 points
x1 mech trooper- 1000
x1 mech trooper - 1500.
it doesnt have to be EVERY promo unit or could even be a way to have pvp-exclusive promos cough cough arena war units cough cough. the units and rss used were just thrown together to provide an example, but I think this would be great for an incentive to play pvp and grind out the shop, could reset maybe every month, week etc?. I'd love to hear others' thoughts on this.
