Fighting in Arena and Lab was bad before but now it's just AWFUL. One good thing, in Lab there was a change so that the battles no longer freeze up at the end forcing a refresh after each battle, however the battles still run like crap. In the Arena it's even worse, I have 4-5 moves all hitting simultaneously on a consistent basis and the sprites of dead heroes still remain on the field making it impossible for me to follow what's going on on a turn by turn basis which makes it impossible to know if victories or losses were close or how to adjust formations to compensate.

Your patch didn't fix anything, it just added more things to bog down the servers further. You obviously don't care about the quality of the game or you would work to fix existing bugs before implementing new content. Of course I have no doubt that this is falling on deaf ears since it seems equally apparent that the Tynon Dev Team doesn't pay any attention to the forums.
