Just a few suggestions for the a.i. - Mobs need to move faster. I've said this before, but I'll say it again, mobs need to move faster across the board. The movement speeds for mobs were initially set a long time ago when everyone had much slower connections, much less reliable connections, and much slower computers. This small change alone would make pvm much more interesting. The fastest mobs, like paragons, should move faster than a character on foot. - Invisibility and hiding shouldn't break aggro. What should happen is what happens when you get on a mount that has a mob aggro'd on it. The mob should stay aggro'd on the invisible or hidden player until something else attacks it. And when a player casts invis, or uses a smoke bomb, mobs should actively "hunt" for the now hidden player. They should stay in the area, and use the detect hidden skill as some do, but they should do it more often, and more than once, and more mobs should do it, and use the reveal spell, as they do, but they should stay aggro'd so that when they reveal you they are on you like marmalade on toast... - Do something fun with the a.i. Have mobs using the reveal skill use a *sniffing* emote, or something similar. And in fact mobs should use more emotes than they currently do, why? Just for the fun of it. Have an ogre lord using the reveal skill taunt the character he is looking for, "Come out! Come out! Wherever you are!" The few emotes there are in mob a.i. are fun, there should be more of them.
