Defensive Stance

[playingtokrush]

No, soloing for my mace/shield Protection warrior is charge or pull, hamstring it if it'll run, rend it for an easy free DPS, and beat the living heck out of it.  2 mobs? no problem.  Hamstring, tab, Hamstring, cleave, use whatever abilities are useful for the mobs you're fighting, cleave some more, rinse, repeat, grab a bandaid after they're dead if you need it. Three mobs? Maybe.  Depends on how high-damage they are, I guess.  Cleave is indicated here, of course.  Intimidating Shout helps in soloing, unless you're in a space where you can't fear them.

I assume you mean that you hamstring runners when they are closer to death, not after the initial charge. Unless you're still at a low level, I can't imagine your warrior (a defense spec'd one, especially) killing mobs in about 20 seconds each. Or is this a "green grinding" strategy?

By the time the mid-late twenties warrior I played could bring a mob down to fleeing health, an initial hamstring would've worn off. Of course, maybe my weapon was much crappier for the level than yours. But I generally waited until a mob was between one-half and one-third health before using hamstring. Fifteen seconds goes by quickly for a sword-and-board warrior.
