I agree with your assessment on what makes sense for the paragon rework. It’s a little odd to me that the paragon system update would remain to be a seasonal only change going forward though. Whatever they do, I would imagine it is going to be aimed at being balanced in both seasonal and non seasonal.
I think being able to get 25 movespeed with 50 paragon points will be missed, so that slot should cap out at 50 points for 25 movespeed, IMO.
As for resource, 200 points is still pretty OP for the 2 resource dumping builds (already some of the highest damage dealing skills in the game right now). I think capping this at 100 points feels fair.
As for Area damage, this feels like it should be capped below its current value. From my observation of Season 29 so far, the main reason some of the weaker builds are still pushing GR 145+, is the extra area damage. This calls into play the need for the boss and elite damage we had from the altar, as I’ve seen many builds detonating high greater rifts and spawning the boss with 5+ minutes remaining, yet still failing to clear. I think simply cutting the area damage per paragon point in half would theoretically make sense, but there are no decimals in area damage values. So, i feel the best solution there is to cap the actual points allowed in area damage to either 50 or 100. IMO, the only universe where 200 points in area damage from paragon is balanced, is one where area damage is not a rollable stat on gear (TBH, I would not be opposed to this, but VERY unlikely as this would mean erasing loads of non seasonal gear). This, to me, is the reason this stuff would have been a great idea to address LONG before now.
As for the rest, I think all the other stats in the other tabs are perfect as they are, and would love to see this CDR customization especially in non season, as this opens up some VERY fun builds that are not excessively overpowered IMO. For example, raekor barb is not that fun to play without stone gauntlets cubed. This normally can’t be done without giving up your third gem for invigorating gemstone, but with the added CDR, we can afford to run them because we can remain CC immune. Is raekor barb suddenly erasing gr 150 in under 10 minutes? No. The other example is the LON set. Some builds are forced to used LOD because they NEED zodiac to function (Wave of Light monk for example). This paragon rework would revitalize the LON set a bit, which is a variant I’m sure some folks would love to play on non season.
Then again, if the altar gives us CC immunity, I guess we’ll be fine. LOL.
