Vine Ogres, worthwhile?

[tratorix]

Vine Ogres are good chaff. They're cheap, mindless so they don't rout and have lots of HP. They're good at drawing fire from enemy spellcasters, saving your better units from death and tying up the enemy to keep them from getting to your spellcasters. Basically they occupy a completely different niche from jaguars. Just don't expect them to ever actually kill anything.
