Only a problem if you dislike them.
I loved alot of the 80's stuff especially Creatures of the Night, that album still stands up today. Love Revenge (90's) as well. By and large the majority of those albums were recorded by Stanley, Simmons, Carr, Vincent, Kulick, and Singer. Yes they had session/guest players here or there but again the majority of those albums was recorded by the core of the band. I also have zero issue with co-writers, I just don't see the big deal there.
As I said above, I had no use for Singer, Thayer era but supported their right to carry on.
Honest question Dan, you said you're hero's like Kiss so why not go back and listen to their early albums from their debut to Alive II. Go back and watch their live videos from Dick Clark, Midnight Special, Winterland, Anaheim, Houston etc... and see why some of your hero's dug the band. It's all them live and barring the few players I pointed above for recording. And 99% all their music except couple of covers and a few co-writes. Hell go watch live stuff of Creatures, Hot in the Shade, Revenge again, all them. Long before the days of sampling and tracks etc... Not trying to convert you, I could care less but it might give you insight as to why some of your hero's dug them.
