Capacity Points are fine right now. Apex monsters are fast enough to kill even when soloing, if you are properly geared and know how to optimize your TP gains and self skillchain damage. Apex Eruca's in Moh Gates are the best imo if soloing. I soloed almost all of my Dancer's CP on Apex Erucas by spamming 3-step double darkness. As my gear improved, it got faster and faster as I started to close 70~99k skillchains with the trust buffs, and I was averaging about 30 second kills. I have even seen a solo blm kill them almost as fast by self-SCing with staff to set up their own MBs.
My point is this. Getting proper gear is FAR FAR more important than grinding Capacity points, especially at the start. In addition to more cp rewards, Apex monsters also serve as an important gear check and practice dummy for higher content level events. If you are struggling with hitting Apex Erucas (which only need around 1050 acc/att to cap), or you cannot TP fast enough to self skillchain even with Koru's Haste II, then perhaps you need more ACC/sTP/multi-hit in your TP set. If your Weapon skills are weak, then perhaps you need to optimize your WS sets to suit the weapon skills you are using. Once you have all the gear you need, then you can start tweaking how you use your job's spells and abilities to improve your CP/hr. In the end you come out learning some things you might not have known about your job. I personally learned about how to minimize JA delay specifically because I solo CPed with Dancer.
So my advice is to use the lvl 125 Apex mobs in Moh Gates as your entry point. If you cannot efficiently kill within a minute or two while solo or duo, then that is an indicator that you are still undergeared, so getting more CP isn't important right now. For example, sure the 100 jp gift for BLU is very good, but if you still can't hit the NM, what does it matter? I have seen 2100 jp blue mages still struggling to get over 1100 accuracy... don't be that person..
CPing anywhere else doesn't really provide the same kind of benchmark as Apex mobs. So if you're not ready to comfortably solo Apex mobs yet, then I recommend sidelining CP for now, and instead run Skirmish, Delve, Escha T1s until you get over the gear hump. There are still even some exceptionally good gear from old content like Love Torque and Wanion Belt (My Rudra's storm appreciates it).
TLDR: If you focus on improving your gear and exploring your job abilities first, then I can guarantee that getting CP will be easier and much faster. There is no need for drastic changes to CP, or petitions to nerf/buff various CP strategies.
