Its not a bad idea really. I know with a few other servers I play on, voting on sky block (we'll use sky block spawn for it) would give you sky block keys to use on like a vote crate specifically made for sky block. But if you voted for towny (/warp spawn for this situation), you'd get vote keys just for towny stuff. It'd be really helpful, but don't know how difficult it'd be. Plus, it'd bring up a new vote crate specifically for sky block, and would potentially remove the use of the creeper that currently provides keys. Additionally, the chances of getting like a spawner from the current lucky crate is really low and basically impossible. At least from how many keys I've used, it took at the minimum around 40 keys for me to get it. Now, thats just luck, by chance. I'm a +1 for this.
