imho First and foremost storage. There is simply not enough of it to go around( if se would stop putting lvl 35 items for crafting lvl 80 it would cut down on the clutter) Retainers are useful for gathering but aside from storage we could use a bank and crafting item bank. 400 slots are alrdy full.

Housing self explanatory... All they need to do is put instance housing in and that would solve most of the problems. Add more slots is putting a band aid on the problem as ff14 becomes more and more popular the need grows.

Tomestone gathering This one isn't game breaking but having one dungeon per patch just makes it boring to gather tomestone that way. We need variety either put the lvl whatever high lvl it is into the roulette or inc the tomestone from lvl 80 for instance roulette. Either way someone thing needs to replace that dungeon that was taken away. On a related note, I know covid really screwed up the release schedule but we cant have relic be introduced in 5.2 and the meat and potatoes in 5.3 and have less than a year to complete it.
