I think it was mostly we all forgot or weren't aware he hits all units in range, which well as Ivan said, can really screw up your healers priorities. For me, it hasn't been a problem at all, Claudia handles the black elder perfectly fine, Lyla is overkill for the average elder on the right but my main issue in the map was timing placements on my first runs which let a few lizards pass through.

FINALLY! At 813, I can buy both Dorania and Fleur as I had planned! And still got 4 1/2 days to keep farming. After them, what to do, I guess I will save up what I can grind for future revivals, Aria sounds tempting to try minCost, but not entirely sure on the long run, a minimum of 4 is required to try minCosting her, but that's just the minimum if luck, Aigis, and RNGesus are on my side during each combination.
