Regarding 1x Experience Rate.

Oh sure this may be something a group of people may endure, but the majority of the attracted audience to this server have been around the private server scene for some time.
I suggest 1-2x Optional experience rate.
Leveling at 1x was an adventure back then, but a time consuming barrier for those who frequently plays vanilla servers/has played on multiple servers.
This will also attract to an even wider audience.
And with this feature everybody will win. Those who want a little bit faster leveling since they've experienced the content countless times before, and those who praises 1x religiously.
The small group of people whom will moan about everybody else not being 1x like themselves, are the people blinded by their arrogance and stubbornness.
Edit: Reflection on the matter, pulling back my "1-3x" as 3x may allow the player to skip entire zones.
