I've noticed a few bug/glitches:
1) Spirit Walker ability that gives ms at lvl 3 gives you 699% ms. (fixed, ignore comment)
2) Had fatals both times when I tried -em mode when all the heroes were healed
Suggestions:
Reduce Orb of desolation (Tier 5 recipe) to maybe -20 armor, -40 is to imbalanced.
Reduce specturn str/hp.
Reduce molten shield to +20 armor, make cd longer to maybe 360?
Stun on oblivion is to imba, maybe change it so theres 2 recipes:
a)Oblivion I-V - Does the damage from 500-700
b)OblivionIl-Vl - Does 400-500 damage and starts with a 1 second stun, 2 second max at lvl 5
Hells fire - reduce damage to 1000? and change the stun to 1.5-2 seconds.
*I also noticed before that denying creeps use to deny all the experiance, I don't know if it does now but could you change it if it did
final comment - Now that there are plenty of heroes to try/master, maybe try to make the map a little more balanced, and fix the glitches
