Are Ultimates a major contributor to Job Design issues?

They inflated most healing and mitigation abilities to ludicrous ranges to accommodate for P10S, and further continued to water down any tactical consideration tied to the battle system.

I doubt it, but they did expand the range of some abilities. This happened because they wanted to experiment with different arena designs, and p10 was the first to fall under that category. It was a pretty common occurrence for DPS to die after Divinding Wings 2, especially if mits were missing or healers didn't sprint. I wish we had Aetherial shift back then...LOL.
