If you want Taunt to work, make it an Aura that works like smelly and that talent that makes melee less likely to focus you.
Taunt: While active, enemies within your range are more likely to target you. Also, enemies inside the taunt aura has a chance to deal less damage to allies.
That's one way to make a tank work that isn't just "Hard CC Damage sponge" that won't work anyway in tactician because fights in that mode is decided in like, 2 turns.
Don't forget that the combat is still purely turn based. Tanks really need real-time reaction for them to work so they can always react. Turn based tanks just watch their friends get whacked and can't do anything about it.
