I purchased SoC and have since requested a refund.

Bug bugs bugs bugs bugs. Buggy AI, buggy terrain, buggy abilities. The new celestial generals vortex ability wouldn't work for me. Shows the blue outline like it's going to cast then fails. Yuan Bo got stuck in terrain twice. The AI sent their entire army to kill him and then one unit at a time went to die to my archers. AI seem to have forgotten how to run down units as they were doing almost no damage at all to broken fleeing units they were trying to kill. Missile units feel more sluggish than before but that could just be me. In sieges the AI sent their archers into melee. Admittedly they were orcs. I didn't even try the other lords.
