it is hard to to the switch but fifa seems so stale, fifa 14 is a much slower fifa 13 and fifa 15 is like fifa 13 with better graphics. The player movements and scoring positions are the same.
They tried to make fifa 14 more "realistic" but that was just to slow. I had a hard time having a decent first touch even with Messi and players like Walcott could not even outrun Demichelis.

And the rain, my god the rain. I played with arsenal, 75 % of the matches were in the rain, it was like playing on sand
EA needs some proper competition to step their game up. I think PES with all the licenses can do that
