Agreeing to all the points above. 64 slots are just insufficient for a long time.

People outsorced sharing of information to discord and websites because CWLS are just not working with that limited space and the game doesnt offer anything else. This means people without second monitor and console players are being excluded from the communities and getting the shared information.

With larger CWLS 256/512 slots (but even 128 would help a lot) and preferably also larger LS and maybe also more than max. 8 LS slots per player we may be able to reach all players in-game again (or at least have enough space for those who need information in-game) and not exclude any.

But also better managing tools are needed like it was already mentioned. For LS there is the workaround to see if the jobs are being displayed in the search info but theres no way to see it in cwls. But even if we get 1k slots, cleaning them to make space for active players is needed.
If its not possible to give a way so see the activity of people ingame, maybe managing tools in the lodestone are possible where you can see the members of your LS/CWLS.

When its being worked on maybe adding auto-rules like "kick after X weeks of not logging in" that can be activated by the owner is possible?
