This reddit thread here expresses some of the things, I've been thinking about FFXIV as a new player and someone who was introduced to the FF franchise through this game.
MSQ gating content seems like a huge turnoff to most casual players,the main target demographic for FFXIV.
A casual player who just wants to hang out with friends in Stormblood areas/do the newest content has to slog through at least 3-4 months of MSQ (ARR to the start of Stormblood),assuming they're playing 2 hours daily.
If they want to get into raids at this point, at least another 2 months to get geared up.
Sure there's the jump potion,free trial and the first 30 days free. However, after purchasing the game,the investment of further time and money compared to some other popular games,which let you get into the newest content faster,doesn't seem worth it.
