Just a heads up to people about retainers. They are a weird left over from 1.0 and we would all be better off if they were removed. In 1.0 retainers sold items like a random placed NPC in a zone. Except you had to check every retainer. If I remember correctly before ARR. The MB is just a search and the retainers still exist in this zone. But instead of clicking on every retainer looking for one piece of cloth, you use the MB interface that searches for you.
They have improved inventory since ARR but we also have multiple expansions of bloat. If the game handled seasonal and cash shop items better that would help some. The materia system will hopefully get a squish with the rest of the game. Creating aethryte gear sets would also smooth out the levelling process. It would help people not save dungeon drops for levelling other jobs. No this would not kill the MB. You know what kills the MB me having retainers with unlimited quick ventures. Also you don't need MB to level like old days they added Ishgard restoration for that.
Also to the person who says it is easy to just go get more. This game isn't really easy to go just get more. Not all dungeons are just like a lvl 80 farming Satasha. You couldn't even do the 24 man even if it was soloable. They could go the replica way they did for sky pirate and make all dungeon set replicas craftable or gil syncs.
Not my idea someone asked about this in a thread. Change all fireworks and such to emotes. Or create a tab like the umbrella tab. The animation is all already done and stuff that give fireworks just make it some other throw away item. This is just one of those things that shows they don't think about space in a concerned way, because they have a dedicated base that defends them. If we admit the game has limitations and we are already working to the max for item storage. Would you not implement thoughtful solutions that are not game breaking. Making all materia lvl one that can fit in i999 gear with +100 is game breaking. Having an event fireworks as an emote instead of a consumable is not.
