I just started leveling my Sader for the group. I plan to use him for damage boosting and extra attack speed while I am pushing greater rifts, but when I am just doing bounties and normal rifts I plan to use wings of the angels for the speed buffs.

That guys profiles are odd. He is using EE on all his wizards and that makes no sense since it does not stack at all. T6 probably doesn't even matter so I guess it isn't a big deal.
