Personally I like Taurens for Warstomp - it's handy to have an AoE stun when your TS's are on cooldown, and for the extra HP.

In BG's I don't find myself getting targetted any more as Taurens than I did as orcs or undead. Of course, being targetted becuase you're multiboxing is another story...

Cheers,
