Seems reasonable, but I still think the 79
is too high in my eyes, for me he is something around 76
in that category, sometimes he lacks in concentrating on what he's actually doing with Maltritz together and he also leaves so big gapes between him and his opponent.
Following values could be...
Top Speed: 78
By the way, Heui made an update some months ago and I doubt he improved that much in Defence, hence I wouldn't go that high in Defence.
