Is the trait a targetable ability? or does it empower your next basic attack? If the latter, the wording needs to change to "Activate to make your next basic attack ..."
Agreed with the other comment, consecration damage is quite high, especially with the build in slow. Perhaps reduce the damage and compensate it by increasing the duration?
Liadrin should have a toggable ability on her action bar (Key 1) so that she can click it and then her next ability is empowered. Makes the choice of using abilities while you have Holy power but not wanting to use it on a certain ability easier.
Holy power only being stored for 6 seconds is a bit harsh, perhaps the power begins to decay after 6 second? (decay 1 power after 6 second, additional power every 3 seconds after?)
Avenging Wrath is too weak. Either the numbers or the duration needs to be increased.
Just a little tidbit, but the wording on spells that reduces damage taken needs to be armor, e.g on Divine Shield, "Activate to gain 90 Armor for 4 second, but reduce your damage dealt by 50% while active." Also, armor cannot surpass 75.
Overall, really like this concept, and i like the idea of specializing how you want to help the team through talents.
Also, I believe that consecration damages too much for a 10 seconds cooldown, though its AoE might be small enough for it not to be OP.
As for the rest of the concept: I really like it and may the Holy Light guide you :D
