/r/ffxivdiscussion: XIV is becoming too big MSQ wise?

[Absurdity]

it will become a mess though when new player start on lvl 90 without knowing anything about ff14 combat

It's a reasonable concern until you think about what the MSQ actually teaches the player or how the MSQ gameplay progresses throughout the story, what it asks of the player.

And you'll find that it's not only so completely toothless but instances of actual combat with your chosen job become less and less in general as you progress through expansions, you could do 100 hours of MSQ and learn pretty much nothing already.
