Dude, stop.
Bon Jovi did fucking nothing to add music. He made catchy songs to get you fucking laid in a back of a Tempo back in 88. That is his importance.
Besides, Winger, Warrant, Cinderella...Why don't you throw in Kix, Faster Pussycat, Nitro in there as well.
Dude, Poison got signed before Bon Jovi broke big. Motley Crue was really the first band in heavy metal to put in a ballad which Bon Jovi capitalized on his success.
