Don't you know? MMORPGs are solo games now. People want solo content, people wants new items at unparalleled speeds without roadblocks, and people want every class to come with an NPC that follows you around healing.
Actually this is where I have to disagree with you. This is kind of what XIV delivered - a more solo experience than FFXI was. Some of it was out of necessity (too hard to party up) and some of it was due to people who have RL contraints. But in the end, what happened?
The playerbase kind of told SE to go **** themselves.
I get being bitter about how XIV turned out - my faith in this game ran out a long time ago. But to say that people actually WANTED the game to be this way..... Well they probably could have taken a snapshot of FFXI just before Abyssea, plugged it into FFXIV, and had an instant success. Just the right mix of group oriented content with a sprinkle of solo play for those who can't devote hard core time.
I definitely disagree that a solo experience with an npc healer is what people actually want.
