I'd like a server wipe (Disco has been so incredible stale for such a long time now - and we'd have the chance to delete some systems too, yay) along with Zelot's(?) recent suggestion regarding changing the credits system to allow for super-expensive things. Make caps and all unique ships open, and set a super-high price on them, reflective of supposed roleplay rarity as well as balance and turn up the severity of sanctions a notch so people get their ships deleted if they break server rules in them - that will help most players behave in their über expensive caps, and we'd also see less of them.
Also the Barge-thing is stupid, it's ridiculous that people who paid 500 million credits last time they were up for grabs can harvest a 9,500,000,000 credits profit for doing absolutely nothing. Delete 'em all or make them purchasable at an exorbitant price, rather than promote negative/passive gameplay.
