Mana regeneration rate and mana recovery rate now work in the same multiplication interval in poe2

In poe1, if you get 100% mana regen rate and 15% mana recovery rate (such as the one from watcher's eye - clarity), you will get basic mana regen * ( 1 + 100% ) * ( 1 + 15% ) = 2.3 * basic mana regen.

But now in poe2, it's not like this.
The recovery rate just works the same as mana regen rate for your mana regen. As a result, the same value of these two mods will give you 2.15 * basic mana regen. For a large investment of mana regen. it differs a lot.

The notable Arcane Blossom is discribed as mana recovery rate but weaker than my expectation and I tested it, found this conclusion.

I hope it is a bug and will be fixed, or the whole cluster is a waste of passives.

Maybe the whole point is just that it works on flask / on hit / on death effects?

Same, i just stacked additional 50% mana regen, I barely feel difference, seems like mana regen is not improved.

Recovery still affects everything, but there are now 'two' types of recovery:
increased/decreased recovery and more/less recovery. Increased/decreased recovery SUMS with other sources of recovery AND of regeneration, thus 15% increased mana recovery is equivalent to 15% mana regeneration for the purpose of the mana regeneration rate, but the recovery still affects flasks, recoup, etc. The more/less recovery (e.g. 50% less recovery from Mind Over Matter) is still multiplicative. Thus, everything "works as intended"
They should change Arcane Blossom to 15% MORE recovery instead of INCREASED, it is very weak now.

Trying out a lot of different builds currently and also made a Stormweaver.
Found this thread, because I theorycrafted in PoB and was surprised by the huge difference in mana reg I had. 'Arcane Blossom' feels completley useless, especially since you need 4 points for it, while 'Open Mind' just does more and you can pick it up on the way.

The wording just feels like a bait, just change it to 'mana regeneration rate' if it works like this or fix it to work properly. (I know now it also applies to mana flasks and other mana gain sources, but you will mainly pick it for the passive mana regeneration).
