My head cannon was always to pair it with the Stormblood era cards so it really would be a huge RNG fest. You could pull a bunch of boles and ewers or you could end up with a bunch of back to back aoe balances.

The balance issues could be managed a little by using RNG weighting, effectively giving each card a pity of sorts. A streak of good cards would leave your odds looking pretty rough for a bit and on the flip side, a run of awful cards could give you a behind the scenes boost for the good stuff.

IMO to actually be viable though, I think it would need to be paired with a shift back towards Sudo’s school of thought regarding DPS checks where the overall damage requirement isn’t actually that high, it’s little burst mechanics and specific phases or adds where stuff gets ramped up to 11.

Even if overall it’s a bit of a trap in general play, I think it’d be worthwhile trade if only to finally give us a healer that isn’t obligated to spam nukes to actually contribute in mainstream casual content.
