I feel like you're using a very...off...definition of an RPG. Have you ever played RPG's? Or JRPG's in particular? Because that's exactly what FFXIV does (and much better and much more than practically any other MMORPG on the market). FFXIV is easily, far and away, the most RPG out there. Heck, one of the biggest "complaints" about it is how much story it has (hint: that's the core part of an RPG).
3.) Roulettes already do this.
6.) Everyone already has the opportunity to have a house. Heck, they even switched to the lotto system so people who don't have time to stand in front of a placard for hours and click can still have an opportunity for a house.
7.) FATE's already do this. And getting "similar % xp" from low-level content goes against the entire RPG concept (you know, that thing you claim to want?).
8.) You do (again - read FATES, Sightseeing Log, etc.).
9.) This would break the game, since fights at lower levels are designed around the kits players have at that level. And it would push newer players away when everything dies immediately to high-level players. This also seems completely contradictory to your #7, where you evidently want things to level sync, but not?
12.) That was done back in ARR. Players themselves rather quickly noticed the "optimal" routes and just run those.
13.) Dungeons have different pack counts. Some also change the spacing between them, include extra pats, etc..
14.) This is one of those things that certain people want, but the overwhelming majority of players don't. Games that have tried doing this anytime in the past 10 years or so end up cratering because of it.
15 and 16.) This is the RPG element you claim doesn't exist...
17.) Why?
22.) Again, you seem to want to cut out the RPG elements you claim already don't exist...also, there is more than enough content for the amount of classes I level.
23.) Boss FATES already do this.
It sounds like perhaps the design of this MMORPG in particular is just very different from what you personally want. Mayhaps it's time to poke around at others and find one that suits your desires?
