Dominion wins

Hey.

So I saw the dominion post and got curious to see how many wins I had in dominion. I knew for a fact I had more than 100 wins, probably around the 200s even. The thing is, when I checked that in the client, it said I had 0 wins 0 takedowns and 0 points captured... which cannot possibly be true cause I played quite a lot of dominion in the past...

So I am just curious what is up with that. Is that something that actually resets every season? Do I need 100 wins in season 6 for the icon?
