Now that Season 2 has been out a while. Do you think ranked actually works as it should?

Reason I ask is that I have hardly touched ranked, but played \~100 hours of mostly quick cash. I'm an average player I suppose but with SBMM in casual it's hard to know where you place amongst the playerbase as you'll always be doing 'ok'.

Tried ranked this evening and the lobby was all bronze/silvers but i'd say the standard was almost identical to my unranked games, if not slightly harder. Is the playerbase just that good that bronze lobbies are HARD... or is the game still applying some invisible hidden rating i've got from 100 hours of quick cash and giving me the exact same level of opponents?
