Horse races are shit.
Not because they are hard, they are very easy really, but:
-Roach controls sucks so much
-if you take a turn on the road, 99% of the time Roach will totally stop
-sometimes there are people wandering ON THE TRACKS: during the last Skellige race I met a merchant travelling on the road, and my opponent run directly in front of him stoppig almost totally.
Who thought it was a good idea putting those races in the game? They are not funny, they are not hard, they are totally useless.
