Ideas to balance leveling and endgame

[Starplayer]

My friend and I were discussing FATE, and how they give ridiculous amounts of exp (don't stop reading lol). From that, the conversation moved into the general balance of progression. At this point, the game is a breeze to 50 (literally 2 days with FATE) and then a ceaseless grind to gear up at endgame. We were discussing ways to change this and we came up with this, tell me what you think:

- Adjust exp gain on all forms of leveling to match dungeons (FATE, guildhests, Leves, Hunting log etc.)
- Raise mythos cap to 400 - 500 per week

I know it sounds simple, maybe too simple and I'm sure you'll all let me know if I'm overlooking something. My reasoning is that every subscription based mmo NEEDS a time sync in order to keep their subs. The problem is that currently, the time sync is unbalanced as it is all in endgame (with the 300 mythos cap per week). This, in turn leads to complaining about both (FATE leveling is too fast - endgame is too much of a grind etc). to me the solution sounds simple, create a balance with that time sync, spread it out so neither leveling nor endgame gets boring too fast.

Using what I have suggested above would mean that leveling isn't a blur, it's instead a fast progression through levels while learning the intricacies of your chosen job, and endgame isn't a long, relentless grind. What are your thoughts?
