Sad no IP...... fast win....... so confuse

I won a game pretty fast, but it wasn't like the other team gave up, they were fighting, and we just pushes non stop...

but what the time we have to reach for us to even get IP? cause I know 9 mins we get it.... but what the min? this was truly confusing we didn't even get 1st win , which seem also abit stupid...

here a pic of the end game to see you don't even get 1st win http://i62.tinypic.com/zkn11d.png
