Largely agree. I do think the mobs needed some kind of nerf tho.

For example, maybe keep them as tough, but not spawning so damn often as that makes it an annoying grind once you learn how to fight them. Then comes harvest, so that would probably require a weaker mob version of aggressive chasing enemies that still have a chance to drop some of the same drops. Sponge as mentioned could use a tweak like possible a way to keep from being so mobile, however, if they added the light OP mentioned then I do not think that mob needs a nerf.
