I have a 87/87 P/W Monk I luv the solo-bility of the class, I have run a number of instances. But as for tanking NO you cant do that, i stack str/patt and stam/patt. I have tried other stating wis/patt, int/patt, stam/patt, for an over all playability not bad but I like the str/patt, stam/patt, I have 3 peices of gear left to stat but over all I have fully buffed 107k patt and 245k pdef, 39.60 crit hit rate, 130k hp.
As for how viable this class is when properly geared/stated in end game content I think rating Monk at a 7 out of 10. At the moment only lvl 77 set gear is available for Monk, with accesories above that. I have Charplan and that is not showing any new sets as of yet for monk, I would like to see the ability to use chain gear for dps as that would take up the overall str/patt/stam/physdeff of the class.
The skills are great to awsome for Monk the main dps skill is Explosion of Fighting Spirit atm its at 85 for me doing 420% main hand without the buff from the pet with the buff 735% main hand dps, My average is 103k dmg. Slash is 86 with a bleed of 8100+, Fighting Spirit Combination 71 gives life back, Ascending Dragon strike is another nice skill it adds 20% to crit hits above what you have from gear.
I maxed out my Healing Salve, Regen is at 73, UH is 78, I dont have any plans atm to raise those but I do also use Bone Chill doing about 1.9k per. I also carry a bunch of Strength of Battle as for most other stuff I do carry phys crit hit rate pots, hero pots, Honey Cake.
If your on Reni holler at me I normally get on at least 4 days/nights a week. As I would like to get in on more runs for mems, stats ect. ect. If your wanting to see what a Monk can do holler at me the name is Sonjur current guild is Blondsrus lol. Im up for anything to further test out end game content
I hope I answered your questions, if you have anyothers holler at me in game or here.
