The idea is pretty simple for every "level" you get, you get a stat point or skill point -possibly both- when your "XP" green bar reaches a check point.
WHY
People want to grind and feel as though they are chasing something, that they are the best at something right? But, people also dont want to feel that the grind is impossible to reach. Take WoW for example, WoW got so bad they had to do a level squish (lv 120 to 60- now back at 70 again with Dragon Flight) because they couldn't figure out what to do every expansion.
Take bdo for example, the gear grind is rediculous because every cycle they have to increase player power by adding more higher tier armor. BDO has the system in place where they have levels but you have a soft and hard cap on levels after a threshold (awakening). So they have two distinct forms of progression that counter each other. The armor that never stops tier chasing, and the levels that never stop. They should have only had one of these, in this case the levels should be kept while the gear chase done away with.
Why for AoC
1. One it prevents the rat race of never-ending higher tier gear chasing every expansion
2. It term of player power, the devs don't need to think of new things every expansion to give players the feeling of personal progression in terms of power.
3. this will prevent the wow mistake of getting all the way up to lv 120 and having to squish.
4. by giving people stats/skill points to distribute on their spells/skills or stat points (strength, intellect, wisdom) instead of levels people will never have to feel like they are "falling behind" everyone else, because levels won't matter.
5. Devs won't feel the need to hit the drawing board every 6 months and figure out what can we do for players to make them feel a sense of progression without bloating the game, when from the very first launch day all the player power we will ever need to "chase" is in term of soft/hard caps on stats points/skill points
Implementation
So basically just like in bdo when you would reach max level you could still level up, it would just take longer (soft/hard cap) and give players the means of being able to stay on their mains wthout making alts. When players in AoC reach "50 stats/skills points it becomes hard capped. So If I have 10 constitution 20 strength 10 defense and 10 movement speed and now I am hard capped, I could get 21 strength eventually, but it may take me one hour for the next increase in player power; and gets progressively longer the more levels you gain.
It reminds me of that old South Park episode of WoW when the fat geek was so OP because he played on that one character for years and the four boys all had to train for weeks to take him down, and it was still a 1v4 that is what I want. Every mmo I play I don't make alts at all. When I reach max level I just wait for next expansion or play another game. I want to be a healer (high priest) and put all my 50 points into intellect (whatever the healng stats is) and when I reach hard cap; after years of traing, I am a Master High Priest and I am the head bishop of the games holy religion (one of the games 7 religions) and I have only played my main and been subbed for four years, my intellects is... let's say 84. but it took me 4 YEARS, (shows how progressively the leveling gets when you just focus on one stat, on one character).
it reminds me of the anime (isekai) BOFURI: I Don't Want to Get Hurt, so I'll Max Out My Defense.
