Suggestion for rebalanced AST Cards

[ty_taurus]

So AST is by far the least impacted by Stormblood than the other healers, and while their new actions are all really interesting and unique, their old card effects still suffer from a severe unbalance. This not only makes the cards feel extremely one-sided, but the shear power of The Balance is what's dominating the healer meta at the moment. By shifting some power to the other cards as well, I think AST could not only have a more interesting time handling their cards, but also make their effects less oppressive for the other healers to compete with.

New Card effect ideas:

Balance - 10% Damage increase (20% on Melee DPS)

Spire - 10% Crit Rate and Crit Damage increase (20% on Caster DPS)

Bole - 20% Tenacity increase (New stat for tanks, reduces damage taken and increase damage dealt)

Royal Road: Enhanced

Spear - Critical hits and Critical heals reduce all off-global cooldowns by 2 seconds per hit.
(Enhanced: 4s per hit; Expanded, 1s per hit)

Ewer - MP Refresh (60 Potency) and TP Refresh (60 TP per tick).
