Actually seems interesting. Are you all going to look into arenas/actual reasons to PvP? The full loot system promotes it however you can do things to make it more integrated. Such as plugin designed war systems, mini-games(conquest) or just simple things like an elo based arena with a justifiable elo system. It makes very little sense to add a whole new PvP systems with no reasons to PvP and with no one particularly looking for it to be a big part of Horizons.
Note: Been a long time since I stopped by don't know if I will ever play or ever want to play again just trying to be constructive and help out a bit.
1. Not quite sure, but there will be a reduced ocean size as has been requested before. The nations are still fairly large.
2. 5 to choose from, and one unplayable nation.
3. There are a few concept ideas floating around, but the Econ staff will be working on that soon. Ideas and suggestions are welcome at this stage.
4. There is a literal duck block. @Dannie gone wild.
