Personally want minigames go before the other major plugins, but if one of the major plugins must go as well, it should be skyblock, several times when i login, i am the only one playing there, tho is going to hurt deeply the time spent there, survival and towny should be saved, for all the members(& SM), donor, staff, and always 24/7 because of the timezone where all we come from.
I love dynmap, that works only in major worlds, i think pern is obsolet right now, it was nice and honest to save it, but what else is the use for it when you can not interact with it anymore besides load chunks for fun.
i did not see grief prevention option, it seems is the one that is not messing with the actual problem, bravo! tho its world is the most messed up with little claims here and little claims there and over there some more, wow! that should be a lot of messy data for storage.
Save Towny, Save in-game Economy, MCMMO should be reset every year for my vote
hope my opinion worth the reading
