See, to these ppl - that's the problem. too much meat. They want to bypass dinner and go straight to desert. IE bypass the story and get into repetitive grinding of the same dungeons, trials, and raids.... as a small percentage of MMO players want to do in MMO's. Read their comments and you'll see... they want MSQ either completely removed for them (ie 100% optional) or gutted for everyone... just so they can get to max level and grind away.
Yes they are a small percentage of the MMO gaming community, that has in too many games receieved abnormally high dev attention for their numbers.
Classic example is WoW - a classic 'raid' styled MMO, where the story (up till say the last 5? years) was completely ignorable and a big focus of dev's was, and is, on raids. Yet if you go back in time to Dev interviews and comments back in 2010-2012... you'll see that up to that point only around 7-8% of their active player base had ever stepped into a Raid. So a MMO that was so heavily raid-orientated... couldn't even get 10% of it's playerbase into these same raids that Dev's wpent a lot of time working on. This is why they were doing things such as moving the top raid from vanilla wow to the base raid in WotLK, working on and adding in "looking for raid", then tying in more and more story elements into the raiding system... to firstly encourage ppl into raiding, and when that didn't work... to force them to do at least parts of the LFR raids to be able to get through the expansions.
If a game such as WoW, a raid-centric MMO, has to use force to get ppl to raid... cuz less than 10% would do it otherwise, it says exactly how big the "rush to endgame and grind" playerbase it. These stat's in regards to raid players was backed up by comments from other games such as LotRO, STO & ST:TOR who all stated the % of players involved in their hardcore/endgame content was small.
As for the "Well, SE already cut some story down so it'll happen again" commentary - what they cut was parts of the MSQ that have been complained about for many years, by both story-driven/focused players and those less inclined to worry about the story. In fact, the sections they shortned are the only area's I've seen ppl stating it was a slog and should be removed/re-worked. So SE have done that... and without shitting over the story, doubt you'll see much more cut from the game.
Going back to the WoW / FFXIV comparison - While WoW pretty much stayed raid-focused (to the point of forcing it on ppl who didn't want to raid), XIV took a different angle. It focused more on the story, and everything else was additional stuff to appease the different taste's of the different players. Mostly story, with some dungeon/raid/trial grinding for those who did, PvP for those who did, glamor for those who wanted to be all pretty & such, crafting & MB for those types, etc.
Going on a personal anecdotal commentary here - I played WoW for just over 10 years. During that time I was a part of various different guilds on different servers. I was in 1 of the top raiding guilds that pushed for world 1st's come dungeon & raid releases (I was in the B/C team, so more casual raiding for me), as well as a few 'casual' guilds which just focused on playing, doing stuff we had fun with, etc.
The raiding guild was tiny in comparison to the social guilds. Our competitor raiding guilds were tiny as well. The social guilds had huge # of active players all doing various different things. Most were slowly working through the story, but some were focused on doing crafting, some were into doing RP (not ERP) stuff, some were just having fun grinding reps where possible without raids, some did do casual raiding, etc. They were hectic as hell with in-game chat going non-stop, multiple different channels on voice-chat for ppl... way, way, way bigger and more active and spread out in what they were doing in the game than the raiding guild.
We also had connections to other social guilds... which were all the same as ours - big, boisterous, full of ppl doing story, old dungeons, crafting, rp'ing, pvp, etc. It's bizarre when you consider it... here we were playing a supposed raid MMO... yet the vast majority of it's playerbase had absolutely no interest in raids.
Back to XIV - I see these threads come up now and again, and it's usually the same tired old arguments about "We just want to get to endgame without paying", as well as "SE should do this cuz there's HUGE amounts of ppl who would come play and they'd profit big time from it", etc. Always a vocal minority screeching for it.
You know what - I support you. Let SE add in a different sub - same cost as the current sub, so no quibbling about paying extra or such.. You pay that sub and no MSQ for you. You'll have every dungeon, trial, alliance raid and raid unlocked from the start. However you can *only* do these dungeons, trails, & raids with ppl on the alternative sub. You don't have to worry about subbing, you get access to all hubs in the game from the start... but can do no side-quest's, no beasttribe quest's... nothing PvE related other than grinding dungeons, trials, and raids with like-minded ppl.
