I know there is a known bug where Colosseum triggers at your feet, rather than on the enemy that you click on for paladins (happens for me at least).
Just started a pounce zon for fun, and I have encountered the same problem. Pounce always triggers at my feet where I cast it, rather than on top of the enemy that I am pouncing on. Has anyone found a fix for this? I have re-installed d2, did not seem to fix. It is the same between sp and tsw. I think its just a visual bug, as in pounce itself should still be doing the same ring of damage around the enemy that is pounced on, HOWEVER it is starting to drive me crazy.
If anyone has had this problem and has fixed it, please forward the solution on!
