simple solution:
expand the list of mvp items that can be converted into certs. either that or increase the NPC purchase value of these items drastically so that they actually pay off. MVPing is supposed to be the main legit way to make real profit in this game and yet the mvps loot tables were never updated for renewal, so you have insanely hard mvps dropping garbage that nobody wants. imo the entire mvp loot table should be redone from scratch, but thats a dif topic altogether.
