Is the way the system is setup currently a bit too open for abuse?
Ie.
Using altar and diplomat and faceless as flux advantage cards. They are sometimes used as very temporary free 3rd domain (cast big cards then sac) (or free sac critters with... doc,research...)
Sinkholes and fresh basic buildings.
Probably some other examples ive missed.

Theres a bunch of people who play them that way now because its quite efficient. Shouldnt salvage be more like insurance against the enemy, rather than eat at Joes diplomat-on-a-stick?

PS. I dont mean the pretty good idea of using them offensively for combat (you havent lived till youve been salvage rushed! lol), just sacrificing.

I don't see the problem.

Sure, you get temporary domain, aand maybe a couple flux out of the deal, but you lose the cards you cast. Seems pretty balanced to me, so I don't really see the issue. Please post examples, if there are any nasty combos.
