Celestial cleansing and the SK drain changes/diamondskin addition etc stand out most clearly in my memory. Good find!
A big one is also the 2handed damage changes.
This most notably would effect things like tstaff monks and warriors with big honking 2 handers.
If you watch the
test of tactics videos, the melees are using 1 handers. This isn't because they didn't know how to pvp, have strong game knowledge or there was something bad in the drinking water that made them dumb at that time.
Speaking directly to Emperor Heartbrand, this
greatly benefits warriors when fighting hybrids. Happy hunting.
