Not a fan of autoblock, not either to spam every 18s my shield guard (spam more when it's bugged and doesn't look my guard is up).

But i'll be a fan if they make possible to use guard as a stance, offensive/deffensive, the guard doesn't wear of until it was canceled manually.

Shield up: More defense, more enmity gain using skill, less damage dealt.
Shield off: Less defense, more damage dealt, more accuracy.
