If there wasn't a tank in the team I suppose that checks out. Supports should be getting Windspeaker or Bond of Stone. Most if not every bruiser or tank massively benefits from Grasp of the Undying. And non-caster marksmen should probably take the crit keystone or the auto attack keystone.

It generally should be more diverse but Thunderlord's decree is a good damage spell in a decent tree that's offering the most raw penetration. It doesn't hurt that Thunderlord's got buffed while two of the three ferocity keystones got nerfed. Thunderlord's or the hybrid penetration mastery will probably get nerfed.
