Gear-wise yes you can, your health is low however.
Get a better trinket than the Repelling Charge. You can drop it and still be over 540, put some time and gold into your JC and make the trinket. Also the JC gems will boost your hp.
yeah, I droped herbalism recently (had it for lifeblood) and will put JC instead (for obvious reasons), and am upping a rogue while getting mats for upping JC but I work long hourse during week, and during weekend I surf as well, so don't have much time. I am however going to get rid of Repelling Charge and try to get the 111 stam trink (blue from AN). And am slowly getting 30 stam Gems while I dont up JCing.
thanks for the tip, i actually noticed yesterday I would be 542 at Defence removing the defence trink.
