Voting for time? I can accept that. I guess it'd be limited to iron+ following their current rank voting system.
Voting for weather on the otherhand, no thank you.
Lot's of players hate rain because of the following:
-Looks bad
-Causes lag
-Makes too much noise
There's an option to disable rain along with its sounds, but the visual aspect is only toggle-able if you have Optifine installed and not everyone knows how/is allowed to install Optifine.
If we end up adding weather features, people with better computers would be at a pretty big advantage since rain can cause Minecraft to run quite slowly.
I'm only supporting the time voting aspect.
