Maybe add the shield shredding ability to some other unit in the cybran roster? Having a specialized unit for this always seemed a bit excessive to me. The absolver so rarely used.
For example, we could add it to the t1 arty or the t2 mml. Hey, then at least one factions mml would be good. Also seems reasonable to have the faction with the worst firebase capability to be the one that is best at killing them.
