Trying to "tank" with one sucks as well. The mighty guard doesn't give any more HP (it should), so a BLU tank will have considerably fewer HP than a "normal" tank.

You can mitigate this a bit by having devour constantly up, but tanks generally have more than 20% of a caster's HP. Needs to be 50-100%

Not to mention their "spells" are casted, which is bad for tanks. They need to react quickly and having a 1.5s spell doesn't help that. Chelodian Gate requiring you to not move is also a pain.
