This is the key issue, however not many people understand how it applies to the PvP side as well.
For instance, most of the so-called 'PvP’ers only cry about high-sec PvP… exactly because they want low risk, high loot drops. They want to farm ISK, they’re just too lazy to do something productive for it, so they want someone else to put in the hours of work and then steal it.
Heck, @Destiny_Corrupted stated clearly they’re looking for “one big kill worth 100 mill ISK rather than 10 kills for 10 mill”. They’re not in it for the fight, or the challenge, or the risk of PvP… they just want easy, fast, fat loot drops and they don’t care what happens to the rest of the player base as long as they get it.
That’s your definition of selfish right there. Also of being a total hypocrite. You don’t see that crowd asking for better PvP in low-sec or FW or null, for instance. They only whine about not enough fat easy targets in high sec where they’re safe.
Then they’ll even blame things like “they just want what they’re entitled to” on the carebears, even though they’re doing the exact same things themselves. The primary difference is that at least the ‘carebears’ don’t require a steady stream of other players to be their victims while also complaining about the unwillingness of those victims to be easy targets, die, and drop loot for them. Apparently, the worst crime these 'PvP’ers can think of is for other people to not give them what they want.
NPC corp tax should definitely remain for the risk/reward reasons. I’d prefer to see some “protection fees” levied on non-deccable corps. In the future I’d even suggest corps be able to use adjustable NPC taxes to alter their ‘level’ of war-dec options.
High-sec PvP is a different topic, but it needs to have more appropriate, balanced and long-lasting consequences than a 15 minute timer and standings hits you can buy off with the profit from your loot drops. Like the rest of risk vs. reward, high-sec PvP is the low-hanging fruit for the worst of the worst PvPers, and should be rewarded as such. If you want decent rewards for PvP then the mechanics should lead you to taking actual risk in actual PvP space rather than sponging off productive players in high sec.
