I think this is intended and I think it will stay this way. It's probably a cap like this on all skills/professions, evader, looter, the only aspect of the skills you can progress on infinite could be the health. I think it's normal because otherwise it could create a gap too big between 5% that go way beyond and the middle group that are around 70-80 - which is probably the largest constant groups of all.
There should be an incentive but it should have very small impact. There could be some cool perks at various stages - like autoloot skill unlocked at level 50-60 looter, 1% crit buff at level 100 in damage. There are many interesting ideas on the forums about content like this.
Thanks for these tests, very interesting - actual rare stuff - useful information in a forum that tends to go a lot these days towards fake news, conspiracies and a lot of toxic debate..
You bring up an interesting point which is Auto loot and I believe that all Attributes need an overhaul like we got with the Skill VU update.
We should allocate something to both Psyche and Intel. Just like how Str increases weight and Agility increase run.
So either Intel or Psyche could be an Auto loot unlock then the range could increase the more you get. Would be extremely nice motivator to pursue those professional attributes and grind.
I think stamina should be reworked too and provide 1 hp per 1 stamina.
On the topic of run speed capped or maxed
realistically nothing should be capped. There is nothing wrong if an avatar can run faster than a vehicle. This is an endless progression game "or at least it is supposed to be" So when you "CAP" things it takes away the core aspect of the game.
If they do a Attribute rework and it is time for one. They should remove all caps and add incentive to go from 110 agility to 120 or 150 to 160. Same for each attribute. Heck hitting 100 in any attribute could unlock something cool. There really are endless possibilities as you mention, like the 1% crit.
It would be nice if all the attributes also provided greater HP gains and in the nature of this MMORPG where content isn't supposed to be hard, 100,000s of mobs are supposed to be done efficiently. The end goal is to basically be Immortal and Unkillable just like other RPGs. Which is why I think the skill update was great but more needs to be done.
The miner unlocks should all provide HP and a rework of attributes.
There is nothing wrong with an Avatar becoming an unkillable god in an RPG with no limits, heck it is expected. It would be cool if MA could officially make some statements on future plans of Skills and Attributes. Only thing planned is Armor requirements so maybe they will change some things when they introduce that as well.
