EA SPORTS UFC 2

The easiest way to get this achievement is more straight forward than it seems. When doing ultimate team you will get to a part that says Ultimate Championships screen. Which will put you against online matchmaking. Which is against players who have played a lot longer or bought their way to the top. If you look below Ultimate Championship it says Single Player Championship. That is AI controlled players. It seems this would be easy to determine from the get go but it is easily overlooked. It counts towards those achievos for ranks in ultimate team.

Side note is wins make your rank go up. More coins are added per longer fights but going for the win is important to rank up.

When making a fighter the taller the height the better. (USUALLY) Longer reach to keep your opponent at bay. Keep them at distance and pound away at their head. So keeping at this way against AI is challenging at some times but more fair than playing real people who bought those players who are better.
