These are all awesome changes!

I do have one suggestion though! Since Leader of Men is now meant only to be a tanking line, I think the -10s marks cooldown reductions of the 2-set bonus should be distributed to each line. Meaning...

Leader of Men 2-set trait bonus: -10s Noble Mark cooldown
Hands of Healing 2-set trait bonus: -10s Revealing Mark cooldown
Lead the Charge 2-set trait bonus: -10s Telling Mark cooldown

I think that would make more sense if LoM is no longer intended to be a buff/debuff trait line. The CD reduction would be a bonus of the trait line that its respective Mark skill is focused on. Perhaps in the future the trait for the -5s To Arms could be adjusted, such as being a part of the legacy or elsewhere, since that is also a buff-focused trait in what is now a tanking trait line.
