Sounds great for PvE! Only problem I see with this is how this would effect PvP, especially since the current subclasses are getting nerfed left and right. I've never been one to call for nerfs, but I'm not going to deny that a majority player base calls for them. With these upgrades, they would get nerfed to oblivion. It doesn't look like there's any drawbacks for activating these (animation times for activation, air time for shadowshot, pause after activation like FoH, etc) to at least try and stabilize the major buffs subclasses would receive. But that's just my opinion, to all their own.
