Current State of End-Game Contents - A Blog Post from A Japanese Player

you are missing the point here what he's trying to say we prefer to customize party size to allows others in fc or ls so they can participate as long as they have the gear IL and have access to events and not only 8 ppl limited . You can do kirin with 8 ppl if you want to but the point is the we wants to have a customize party size so everyone can participate on fc and have fun together. Try to run Binding Coil of Bahamut with more 8 ppl or lets said 18 it will by more hard them with 8 people with all the mechanics they have right now . Binding Coil of Bahamut is raid contend limit by 8 ppl only the system doesn't allow for more ppl on cuz Se made that way is more easy for them to have 8 or lest but they can change that if they really want . sky and dynamis or sea are open world content which is what we need more on FFXIV.
please forgive for my poor english.
