[quote=Tatsua Aiisen]Gawain is already one of if not the most powerful of Sabers currently confirmed[/quote]

Indeed. But at least canon Gawain is either effectively invulnerable in his preferred conditions and merely good out of it--appropriate for the second greatest knight of the Round Table. This one's skills alone are swingy as hell.

Also, he apparently can't ride a horse. A-rank Riding is mystic beasts and the like. B-Rank is 'good driver'. So this Gawain is apparently bad at horses.
