Are lava warriors overrated?

[Kelan]

Hmm, I am by no means an Abysia expert, but if you use the best defensive infantry to take the inital charge from the enemy, then have your lava warriors flank in from the sides to do damage, they seem to work well.

I do recall still losing a fair amount of them, but they can really deal out some damage. To me, they seemed pretty powerful when I used them a short while back.
