Earthrobot - pls buff it somehow

I think you all give too much usefulness to the damage reduction. A -20 % is the same as if you add 20% to your hp, you need 10k hp to get a bonus of 2k... Is it really great? The shredder and the gob have a better ability. May only 15% but more speed.
Having +80% hp for 5 sec... Sorry but i really think that it is creepy :p
Qweqqweq you suggest that this ability is linked to the ultima. Isn't this sad you must waste a skill just in order to use a weak ultima? (as said above, hunter's cloud is much more better)
