I agree with BabyBlueberry I've admin on MC servers, one biggest issues is toxicity, and difficulties to enforce the rules. Toxic is when - your players are verbally attacking each other repetitively, swearing R Rated if not X-Rated things at one other. Staff gets worn down when it's daily and if the ownership does not backup the staff. Mine does, but there limits, fearing players will leave the server and no one comes back. Unfortunately it's double-edge sword.
As a player of Mod Minecraft, i find the changes not so great. it adds some extras so the game for sure. However, those with mods such as Movecraft it's headache and causes older mods less likely to be used.
I have yet see it used on a modded server. Its going take work to adapt it. The navycraft oriented servers (big ships moving) going have be REALLY revamped because water works differently and additional blocks.
Vehicles move have to have blocks assigned to it so it will work or the block disappear or worse sink glitch your vehicle in to a building. :P
Thanks Mercy_. I still think its a crime they shut it down. I didn't know it wasn't really the official one, it claimed to be. I like it just the same.
