I am a little bit surprised that so little people have voiced their opinions about monster combat mechanics, I can't say they are terrible as of now, but I think a lot of improvement is needed. Here are my three biggest concerns:-

1) All mobs have ranged attack and that really grinds my gears. It's very annoying and unrealistic when a squirrel spits or hurls a seed at me after I taunt it.

2) Mobs are reluctant to move out of their spawn territory? I Taunt a Maidenbug from outside of its little spawn enclave and it just wouldn't chase after me. I did something similar to a bat a long while ago and it would just run back and forth between hitting me and returning to its spawn point, regening in the process (I don't know if this has been fixed now).

3) Most mobs I've encountered so far only had one skill move which they use every 10 seconds or so, and I must say it's getting duller and duller as I level.
