Recently when I was exploring with a friend of mine I put him on follow while he was on a drake and I was a bird, I noticed after a few seconds he went way far ahead and I stopped following him, I hopped on a mount of mine and followed again, I was able to keep up with him easily. We both had the Mount Up guild perk.
Is that fast speed increase where he was able to outrun me really 10%, or me missing out on my 310%?
