spin is a buff rather than a nerf. On retail ms did not increased ticks of your spin. Dbog buffed it way to much and just lowered the buff.
With resistance yes we have a cap but at the same time resist formula is not the same as on tw. Maybe you have more resist in dbog than in tw. We don't know. Ulti is still in a pretty good spot there is no reason to buff them anymore.
Crit dmg got nerfed pretty hard which was an indirect buff for all tanks including ultis.
