This makes me wonder whether, given how negatively AST players reacted to the new all-supportive cards to solve the damage-vs-support card imbalance, the opposite would work better, all cards are about dealing damage, and that kinda becomes their "enhanced" damage kit to try focus healers more on dealing damage given how there's never much to heal for the 20+ healing buttons healers have.

In this case I could see the same 3/3 alternating cycle, one cycle the cards are self-buffs and nukes and debuffs used on enemies, the other they're buffs used on other players that enhance attacks, but they kinda "fake" a flat value. They last until X amount of potency of damage has been caused. (which is a type of buff/selfbuff FFXIV would do well to bring in, in general - we have so many balance woes caused by stacked interactions of percentage affects, both X-damage-enhanced and Y-PPMs would be good alternative buff types)
