1. How do you feel about the general state of job design in Endwalker in contrast to past expansions? Do you think this direction is good or bad for the game long term?

I think the job design is rather poor and getting worse as time goes on. They focus too hard on removing any kind of pain or failure points in a rotation and thus remove any chance of skill expression. Almost every job except BLM (wonder why) has had their skill floors put into the dirt with the ceiling being only a little bit higher.

I also think they ruined healer gameplay going from SB to ShB. Just homogenized the heck out of everything.

2. Which expansion do you think was the best for job design as a whole?

Stormblood since Shadowbringers was when they really started homogenizing everything. HW was good as well but had some questionable designs like bowmage bard. I did enjoy Summoner in Shadowbringers though, before they ruined it in Endwalker.

3. Other live service games generally release official surveys fairly regularly. For example, Genshin Impact usually has a new survey near the end of each patch. These games also reward players who take these surveys with in-game items or resources. Should FFXIV be doing this too? What kind of rewards would incentivize you to give feedback on new content or job changes?

Surveys yes, rewards no. If we really want a reward, I would just do something basic like those gold or silver chocobo feathers you get from refer a friend.
