hey pelotora! sup buddy, i think ive seen you around 19s. I just recently finished my 39 monk. his gear is, in my opinion best in slot. at this point, i have several sets, so i hope the right one is on right now when you armory him. regarding your issues on squishiness... it is unfortunately all but too true. i wanted to go windwalker, but found the spec lacks the survivability to do anything productive in gulch... the mobility is there but by the time youre finished your first fists of fury you probably have to flying kick the fuck outa there. I instead chose the route of brew master. it has insane survivability and mobility, AND SURPRISING damage. i was topping the charts simply from dying so rarely. ive found this class also aids the team most productively because of the countless slows/stuns and PEELS you can provide on defense - not to mention you can even fc! I hope my monk is currently rocking my favorite set which is a hybrid tank/dps gear set. it is a very pleasant mix of agility and stamina in order to have superb survivability on defense, and at the same time putting out significant damage. definitely worth looking into!
my 39 monk is Cashrules on horde side Laughing Skull
I would recommend aiming for the cloak "Cloak of Coordination". the cloak is a 350+ ilvl piece so u can slap on a fat 30 stam / 56 pvp power on it and go hard in the paint. unfortunately, its difficult to get. you have to buy it from a guild vendor after joining a guild with a special guild achievement (i forget this achievement but you can look it up very easily). once you join the guild, you have to do appx 3-4 hours of hard quest grinding to get to honored reputation. once ur honored, by 3 of those babies from guild vendor and return to your preferred guild. well worth the time. hope all that info helped and see you in the gulch!
