Combat Log causes a ridiculous amount of FPS drops. It's absurd.
On another note, the "buff to Armor degrade" seems to be ... them nerfing it. It doesn't stack nearly as well as it used to. I used to be able to shred Armor to 0 regardless of the starting value, it seems to now be limited to however many swings you get in a 5s interval (the duration of the shred).
Means that I need to make a lot of adjustments to my test setup for Armor shred.
Edit: Also, console items seem to be flagged now. Neat. My test characters are now all officially cheaters!
It seems like only if they are created after the patch.
