Petition to Save the Moloch!

The Moloch has a base Prot of 15 (same as all Devils) so there is no need for Earth Magic outside of those who have played with too many VQ's. A suit of armor will put him in the upper 20's which is by and large close enough for protection purposes.

I like the Moloch, I don't like his imps however, but the Imps do not make the Moloch 'useless' in any role other than a Blessing Strategy. It only makes him at current inflexible in his SC role early in the game (which is where SC's are most valuable).

AFAIK it is not the intention of IW to keep the battlesummon creatures routable as they are and finding the reasons why and modifying them to the vision of IW to work how they see them is in progress. That is the only answer that I can give you with any assurity.
