You should have seen the game I had with Cow on the night of the 12th. I led a pretty brutal team let down.
1st I got UI lag with Oak and ended up taking soul power at level 2 instead of divine justice, after specing for assassin.
So I respec to minions... and 1/2 the time they are just floating around ignoring attack orders.
Then the orders lag was so bad I couldn't for the life of me interrupt the UBs spits with pent or pull back without walking into tower fire.
At one point the game cleared up and I was interrupting the UB with ease and harassing like crazy with spirits, but it was way too late by then, and the orders lag started up again a few minutes later.
Regardless... I died 4 times, which does not happen! (because in turn it means my teammates start to die because the other side has been fed to much).
I dunno... lately it's not that the game isn't smooth, but orders and UI interaction take forever to register. You also need to be damn careful when pressing the N and M keys to move minions around, because if you do it too fast the orders are ignored and it's easy to get stuck moving your DG the wrong way.
I have a crazy conspiracy speculation that all the various UI mods are causing this problem...
