I have done some tests on both Pendragon and Uthgard for berseker and the rest of the tanks from same dmg table, and for hibrids that include paladin,skald etc.
There is no -10% melee dmg for these tanks, perhaps the damage variance tends to give more chances to make lower base dmg on uthg then on pendragon but i cant really tell as i should make tests for too many hits, but the values r correct .
Here is an excel file where you can see and understand better: http://www.mediafire.com/?knuqyigj0my
The file its in a working progres, i m surious how buffs affect on uthg melee dmg for pure tanks.
Thank you
PS : There r no pics posted, i have them but i can asure you the numbers are 100% correct.
