its getting better... but there are still problems, most of them are minor and easy to fix.
1. the stars/lightning bolts only appear the first time you cast it. if you cast it another time there are no stars or lightning bolts
2. he says "lightning" and "you ever get hit by lightning where the sun dont shine" at the same time
3. if the player has no control, pan the camera over to where the action is taking place.
4. the large number of footmen/knights waving thier weapons can make the game lag. if you took out 1/2 of them it would make it run better

5. if you have multiple creeps spawned at once, kel-thuzad sometimes runs off and attacks them instead of staying there waving his staff around.
6. the creeps still attack the lightning ball.
if i find something else i'll let you know.
