Frankly, IMHO....potentially one of the most original in a long while. But, an epic fail. More per mob isn't fun, it's boring. And nerf the one shot kills in story mode. I only had that in the bonus boss, story mode. I beat the final one, but died after from the BS number of the rest of the adds. Sure, make it harder a bit, but not darn near impossible in any but a tank. Literally lagged so hard, due to sheer overwhelming numbers, I struggled on a healer due to lag spikes alone. And, I'm decently geared, as well as over-loaded on Memory etc. It's the FP, not MY gear. In game, nor IRL.
