Just got an epic Kentro and at level 11 it is completely inferior to my level 9 Wuerhosaurus.
The Kent does 100 or so more damage but has less health, no armor (makes the descriptive text very inaccurate) and slower. My guess is that with two more levels my Wuer will exceed it in damage. Oh and both have identical attacks with same cooldowns.
Why is Kent an epic? Completely inferior. Is it that big a benefit that you can hybrid it? Is that enough reason to have such inferior stats?
