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.
They really should design some warfare skill works similar to Reactive Shot so you can actually *guard* an area and do opportunity attack to who ever try to enter the zone. That's a real-time reaction tank needs.
