Today it took me 3 hours and 41 minutes to beat vMSA instead of usual 2 hours something. Not only I run out of mana and stamina faster and have lower dps vs daedra, but mobs appear to hit harder. Level 5 was full of oneshots by groups of ranged guys, level 8 firemages' channeling attacks have damage comparable to level 9 final boss channeling spell etc etc. I'm not very good at vMSA so before the DB patch my 15th death was usually at level 8, today it was on round 3 or 4 of level 5.
The thought of mobs using their champion points is ofc a joke, but something has definitely changed. I compared death recap screenshots before and after the patch and noticed that lvl 9 last boss's necrotic blasts has indeed higher damage. Sometimes its only 5230 vs 5290 but other times it is as high as 7k+ vs fully repaired armor.
Try it for yourself and say if you have noticed these differences.
P.S. in my today's vICP run a random harvester killed our entire group, which has never happened before. Though the dungeon is much much easier as a whole, it seems that some of the mobs there have increased damage too.
