Berserk is nice, although I have some doubts about it. Have you noticed that sometimes your Paladin has full energy bar, but the 2nd proc doesn't happen immediately? Apparently Paladin's proc has a few seconds cooldown (around 2-3 seconds) inbetween procs.
I did notice a slight delay but figured it was either a bug or my imagination lol, but it being due to divine shield having a cooldown makes much more sense.
Stone Skin / Tenacity are just talents that're good for Paladin as a tank, I would prefer those talents to be used for raids instead though. Although in an extended boss fight without perma chain-stun where you're making your Paladin tank for a long time I would prefer stone skin for higher damage reduction rather than higher base HP for the strategy to have more sustainability.
This has been the playstyle i've been hoping to achieve eventually (pretty much why I put my AC on the shelf and started lvling my pally). I've been working on getting my champ lvld up but have been hoping to find an alternative strat for boss 1 and 2 where I can tank (hit and run gets real boring real fast lol) without neeing both champ and tg chain stunning.
Very interesting idea with using the shaman to reduce dmg...unfortunately all the shamans ive rolled have been tossed straight into other hero skill lvling haha so cant test this anytime soon. A high enough level pally with stone skin may be able to handle boss 1 and 2 on his own without needing further dmg reduction form a shaman I imagine?
