Alternate Unit Rules

By Ignatz_Von_Zwakh, in Nexus Ops

I was just curious as to how people feel about the alternate unit set. Personally I've been finding the alternate units (Clones, Sporlings, etc etc) a little OP when compared to the original units. I'm thinking that perhaps I'd best restrict my gaming group to picking one set of units prior to battle so were all on equal playing ground rather than having such a clash of disparate forces.

So, anyone else had similar feelings?
