I legit found feast a lot easier in fine. It had a certain skill floor because it was execution and meta heavy, meaning players HAD to know what they should be doing exactly to perform at a minimum welfare level. That issue got also exacerbated by the fact that especially below diamond, healers made or broke 99% of games and whoever had the better one, won, period.

Once they learned what to do though, it was just extremely mechanical and repetitive. Half of the things were already settled by macros (that every player also had to have prepared, reinforcing the need for everybody to KNOW what they were supposed to be doing):
- countdown burst attack targets on melee DPS
- silencing/stun macros on ranged jobs targeting the enemy healer, facilitated by every role always being in the same party slot, and synched on the burst countdown
- tank stun synchronized with the burst countdown on the target

The remaining half were the basics like positioning and hugging walls which are also part of CC. But most of it was always following the exact same pattern, and the team executing the same script better than the other eventually applied more pressure to targets until they were out of medkits and started dying (provided both healers were of equal skill). Feast had a higher skill floor perhaps, but a way lower skill ceiling.
