Kayle support 4.2... good?

I just did a TB match where I went Kayle support... I picked up frostfang and was able to make quiet good use out of it's tribute because of KAyle's harass ability between her Q and E... it seemed my gold income was very high! In fact I finish pretty much equal in gold income to the other teams carries.

Has anyone else experimented with this combo much? Sorry if this is a old topic but I've recently come back to game. :)
