You're talking about two completely different issues here. What does that have to do with level cap? If players aren't going to do old content, then they aren't going to do old content, regardless of level caps. If a player needs to complete old content to advance, they'll have to find a party, and I doubt that required level synching is going to be the difference between 'Sure, I'll help' and '**** off'.

You're also forgetting XIV's fundamental difference; the game is designed around leveling and maintaining multiple jobs. There's always room for advancement because multiple skills from every job can be shared. With proper level pacing, there should always be a large percentage of the player base with something to gain, whether it's experience or gear for all of the jobs you're expected to level.
