What is the problem with the cp system? This is a question i asked myself while levelling up psjiic, and i think i came to a good conclusion, keep in mind that this is my opinion.
One of the big problem with the cp system is that because of the sheer amount of power it gives, much of the old content is now pretty much irrelevant, you can do more damage, you have better defenses and sustain, personally i really like progressions systems after you've hit the level cap, like the artifact weapon in legion, i personally loved that, so, what is the problem with this system?
Many say, that cp is the problem in of itself, because it gives so much power, to balance this, they have to nerf, take away something from the classes, which of course is not good, but i do not agree, i do agree that this is a problem, but i do not agree that cp is necessarily the problem.
When this system was made, zos knew that sooner or later it would cause these kinds of problems, to not think that it would would be naive at best, cp has already got a pretty massive nerf.
When this system was out, you would gain more and more stats the more point you put into the system, up to about 50% more base stats, that 50 % has been reduced to a flat 20 % at cp 300, considering that many run around with about 43 to 50 k mag for magicka builds and about 38k for stamina, it doesn't take much explanation why this is a pretty giant nerf for the system, so what is the problem? The problem is that zos made a system without really committing to it, this is the problem, in other words, the problem is laziness, they still seemingly refuse to make a new harder mode for pve, one that is balanced around this massive increment in power, you could call it something like legendary mode, and still refuse to balance pvp and pve separately, zos says that they wanna have a "feel" for a class that stays the same in pvp and pve, and that might hold some truth, but you don't fool anyone, the real, the first problem is that this would cost money to make, probably more than what you are willing to spend, because you would rather have those resources into making new useless cosmetic items, or new content, without realizing that this is also just as important as dishing out new content, if not more, but hey, if you put out a dlc, you can be sure that at least some people will buy it, but if you re balance the game, you can;t be sure just how much you will gain from it, but know this, sooner or later when a new, much better game comes out, don't be surprised if many leave eso, for a game where the devs actually commint to the systems they create.
In essence, progression systems are good, in my opinion of course, but when you launch said system, you should also fully commit to it.

I'll add another point, to clarify 1 thing.
There are 3 possibilities on why the devs don't do this.
1: devs are lazy.
2: devs are not lazy but higher up won't let them change these things, because they would rather have them spending development time on crown store items, and content.
3: both are true.
