I would link taxes and services to Factional Warfare. It’s stupid that one side can essentially lose the war (lose all it’s contestable space) yet it have zero impact on that empire. The nature of a militia is that of citizen soldier, not professional as is the case currently. Having an impact on the everyday miner in high sec would do alot to encourage people to put down their mining lasers in favor of a gatling variety, if only to improve their own situation back home. (you know, sort of how militias work…)
Bring back racism. CCP should have left alphas linked to the race they chose at character creation. CCP creates all this great lore to immerse you in the game, then promptly abandons it. Why are we even forced to choose a race if that choice makes absolutely no difference whatsoever?
You should not be able to be christened a capsuleer by the mortal enemy of an empire only to be able to openly waltz across the border to the trade hub or be employed by the security apparatus of that empire (all that is replicated for each empire already).
Fix the Risk-Reward balance. Which means either high sec gets a lot harder, or the rewards get reduced to dust. For the amount of risk actually present in high sec, it should take a month of grinding to afford a Rifter, yet month old newbs are on the forums asking about which Marauder to throw a couple billion at. Ridiculous.
Ultimately, I think CCP wasted a perfect opportunity to make the first decade of Eve about the Rise of the Capsuleer, and the second about the fall out of new empires emerging- and pit the NPC empires against Sov. Transition FW to aim at sov- the NPC Empire loyalists versus the break away empires planting flags independent of empire rule. Point the two biggest PvP content groups at each other and let the lead fly.
Instead Eve remains not one game, but really a series of smaller games people carve off and ignore the entire rest of the game to do. I’d like to see a much more integrated New Eden.
