I suggest to make all abilitys that are like 5 seconds recycle, 1-2h duration, self only and activated all the time passiv.
Abilitys like
Savety
Melee Ward
Energize
Elemental Ward
Primal Roar
Determination
This would save Timers on server and hotkeys for players.
Some abilitys like Skin Like.. , Lifegiver, Aceleration, Vivacity alraedy got passiv long time ago. But this change left out a few schools with nearly identical abilitys (mage for example)
