Do not force level caps on content - You segregate the player base

[Antipika]

That's why forced levelsync/scaling for low level content would be great?

If done properly, yes. (Like Rift's mentoring).

If done like on XI, nope. Enjoy Level Sync no armor bonus edition. The scaling was horrible because SE wanted to preserve the usefulness of low level items for capped content. In the end, it was more or less the same. Without proper gear you would be almost naked stats wise. Even items that were just couple level above the cap would suffer from terrible nerf...

You know what's not fun? Cheesing content. What's the point in it being there if you don't actually get to experience it the way it was intended?

I don't need someone else to decide what's fun or not for me. If I have fun "cheesing content" that's my problem, not yours. Everyone is free to say "I don't want the help of high level players to clear the content, I will try with a normal group".

Because everyone most people tend to rush toward endgame, and the people who actually want to do content at the level its provided end up suffering.

Too bad for them if they rush, again these people doesn't influence my gameplay. If they want to ruin their own adventure, so be it. If they have fun that way, good for them.

You can't have your cake and eat it too. You can't please everyone, and you can't design a game around working with every possible preference. You have to pick a direction and fully devote yourself to making those design decisions as fulfilling as possible

Go on, try seeking a party for baby Ifrit and requesting only members of the appropriate level. Actually, I'll save you the time and tell you what'll happen: You're not going to get a party. Why is this? One, due to the pace of leveling, players at that level range are a vast minority, and two, there's no incentive to play a level appropriate class when you have maxed classes. It simply won't happen.

Now, if there were caps with rewards for completing the quest multiple times, the content is properly balanced and people make constant progress, whether they're completing the quest, or getting seals/money/whatever for helping another. Throwing that all away because some people 'like cheesing content' is foolish.
