give your "squishy" characters stuff like fortify and bone cage and they're no longer squishy
there are enough defensive options in the game for each role (from armor to invisibility to evasion and beyond those) that i've never felt the need to have a tank, but if you do want to build one it's perfectly possible with sword and shield (you sacrifice damage, although bouncing shield scales amazingly throughout the game) and use positioning to make targeting your mages less of an option for enemies
instead of having one character just taunt everyone you need to do a little tactical work in order to make "tanking" viable, but it is
edit: i will say that taunt needs to be reworked as it's currently useless. maybe have it act as a "use auto-attacks/single target abilities on the taunter only" thing instead of simply being unable to target other characters with single target spells. enemies who are taunted can still aoe the rest of your team to death, and this presupposes you're taunting someone without physical armor instead of just knocking them down or crippling them
