New emotes for veterans and total playtime

I would really like to have something, where you can see how much time you have spend in-game? Now that you've announced that players, who has been playing a lot are getting special emotes depending on how long they have played, I have been playing A LOT since the end of season 3, I'm so excited about the preseason but I would like to know if I even have a chance to get conquerer of the league and how much it requires, I know it requires 2500 hours played, but is it excatly 2500, or how close to 2500 do you need to be? I have been playing co-op and ARAM, dominion and featured game modes, do they count as in-game time too? :)
