Seeing as OCP is a constant that can't be undone, and it is fine to pay for gears equally if not more powerful then even some MVP cards, I think the cards should be phased out.
With the exception of a few cards, all should be remade as an actual piece of equipment with similar if not exactly the same effects.
The drop rates for the items should be increased to 0.5~1% base rate.
I mean why not, there really isn't a reason to keep the current level of RNG when the average user doesn't want to deal with it; and, OCP items will eventually replace 85% of MVP cards anyway so yeah.
