Staying toe-to-toe with any kind of melee (except rogues... poor rogues) is pretty much guaranteed death, as we're scarcely more resilient than clothies. Trying to bleed-kite a ranged is pretty much suicide as well, since most range classes are fully dps effective at 40 yards while you're hoping your bleeds will even do 30% of their health.
And the fears... don't get me started! Getting feared with 135% movement speed is so awful. Especially when it lands you farther than the range of your gap closer. If you happen to have a DoT on you, good luck trying to re-stealth and re-engage.
So what am I doing wrong? L2P? I kinda hope so, but the suggestions people give seem to vague or over-simplified. "Just bleed/kite them!", "Use barkskin when they blow <cooldown>!". Yeah, I do all of that. Maybe I'm doing it at the wrong time. I have tons of macros for power-shifting, focus CC targets, charging, keeping rejuv up, all within easy access. Maybe I just suck. Any suggestions would be appreciated.
