One final argument on this topic as the poll wraps up, I see a lot of players exaggerate the implication of upkeep, implying it would add too much tedium. Even with vanilla upkeep, you can cover an entire wipe with less than a day of farming.
Another argument is players unable to build large community centers. I disagree. If it's community-oriented, you can utilize drop boxes to receive donations from players who utilize your space. You should have no problem covering upkeep on a large community center when you've got several players contributing.
The key takeaway from upkeep would be the elimination of random empty bases, randomly placed foundations deployable throughout the map, and the natural limit to the player's ability to build outside of their means. I understand a lot of people play this way, but in this case, you'd either need to put in an effort to maintain your large base or try a more creative-oriented server.
So consider your vote and ask yourself if adding a couple of days of farming to cover upkeep is worth the elimination of thousands of useless entities and abandoned bases cluttering the map. Also, for our more survival-oriented players, the lack of massive buildings tanking their fps as they go around the map.
It's important to understand that if you're on the fence about this change, this is something that can easily be retracted if it has adverse effects on the server. So if you're learning over, I'd recommend giving it a chance vs. playing it safe.
