also make a spell thats the opposite of barrier one that pulls units in ward.
make a suicide bomber like techies in dota not a hero but like the unit that it was based off (sorry i don't know name cause i haven't played real warcraft in a while). it would help beat a lot of things. Imagine just sending in a couple of those and having them commit suicide it could kill golems and potentially granites.
make a land mine spell/ item so it explodes when passed and a static ward so it stuns when passed.
taht omega wave looks pretty cool, in essence its just an OP firestrike that doesnt damage enemy units and drains mana, cant have both. if u want mana drain, it would have to be very minor. now if its an ulti, tahts a diff story. http://chf.ucoz.com/forum/71-3499-61942-16-1396993348
