How about not 4 people for 20 jobs? How about at the very least one main for each category of job? I don't even know the second part of your post was about, but I happen to live on planet earth. If this game is both keeping a company afloat and being paid for by its playerbase monthly, I'd hope its company would invest in it more to keep the trend going.
Maybe you weren't around when a big portion of the FFXIV team got poached to work on other projects or when SHB didn't have enough funding for a deep dungeon but they sure were investing in FFXV and the travesty that was and is FFVII:R but I remember. Do tell me what we have gained since 4.0 in terms of content that wasn't there before? How did the volume increase? No, better shot scenes and voices don't count. The MSQ is important, yes, but I'm talking about things that will keep you playing here and add variety. What have we gotten? Worse job design by miles? No hard dungeons? Bozja? No two ultimates? No deep dungeon which I mentioned above?
I do think they're trying to make more meaningful content in EW given the plans for their harder 4-man content, the supposedly custom dungeon, the much needed PvP revamp and reward system, the island. But come on, bro.
