Why does this always happen in this game? Rather than bring other aspects up to meet the levels of efficient methods you guys nerf things down to unplayable levels for normal people. There are already daily complaints about the level of grind and 3-400 hours or more required of unengaging gameplay to reach level 100. Nothing in power play is engaging enough to warrant this time commitment. Those that want levels shouldn't be forced into a system they don't enjoy for that long, they will just quit and play something fun, and those who enjoy power play will stick around regardless.
Rather than make combat and bounties and other entertaining aspects of the game worth more merits you nerf the only efficient methods available and kill the fun yet again. These are lessons already learned...combat used to be worthless then after years of complaining it was buffed (while killing mining). Now a new system is introduced with all the same problems and terrible solutions. Just let the game be fun and let players finally enjoy themselves. I've spent 40-50 hours trading in rares, I dont enjoy trading but nothing else is as profitable, but it does take a lot of time. Why can't I enjoy the reward for my dedicated hours rather than being nerfed again? I ran the leesti blockades of other players in open for days sometimes barely surviving the onslaught of frag cannons. It's the most fun I have ever had trading in this game and now it gets nerfed...
If there were exploits that's sucks and needs to be addressed, but so do the abysmal levels of merit returns for combat, exploration, and mining. Bonuses should also be applied for playing in open. You have commanders really getting into pp and defending their systems from invaders seeking rare goods, if I'm running goods in open, or if you're killing my trade ship in open we both deserve a bonus for taking the increased risk. You will never make pp open only so at least give a bonus to those willing to take the extra risk.
TlDr: learn from past mistakes and buff systems rather than nerfing everything players enjoy before you kill this power play too. Try to make the game fun rather than a second job. Reward open players for the increased risk.
