Arcane Blossom and increased mana recovery rate
If you look around the passive tree for mana nodes, you may notice that while the vast majority of mana nodes will provide increased mana regeneration rate, arcane blossom instead provides 15% increased mana recovery rate. Since these are clearly different terms, I had assumed that increased mana recovery rate would be multiplicative for mana regeneration. After looking at the wiki, that's also how it appears to have been in PoE1. However, after some quick testing, that does not appear to be the case.
My mana recovery per second from regeneration is 88.2. Allocating Arcane Blossom increased it to 92.9. I have no other sources of increased mana recovery. It is certainly not acting as a 15% multiplier. It's not clear if this is intended or not. Increased mana recovery does still act differently than increased mana regeneration because it applies to other forms of mana recovery (I tested with my mana flask just to confirm,) but it may be less worth investing in if you're trying to rely on regeneration.

Do you have MoM allocated by chance?
Interesting. I can see why a game designer would like that. Making similar sounding stats additive is both easier for new players, and helps keep a lid on player power.
It’s of course a bummer when you were hoping for a multiplicative boost.
Why would it be multiplicative?
The wording simply means you get increased recovery from all sources of mana gain not only limited to regeneration.
It also probably includes the mana recovery your get from flasks or leech.
That makes that node pretty bad then. I wonder if that is really intended. The 25% mana regen close to INT start is a better pick then.
There is a Notable that gives 20% of damage taken recouped as mana. I assume the recovery rate applies to recoup as well.
Mana recoup also appears on gear and running it with MoM seems to be a viable regen option for any Sorcs/Witches.
In fact, given that flat life is only given when stacking Strength, ES% and mana regen/recoup are the main EHP/regen options for Sorcs/Witches. This is especially true if you're going Blood Mage, but people really haven't caught on. You really have to shift your thinking away from PoE1. Looking at all the ES% and mana nodes on the tree, Sorcs/Witches have insane EHP potential.
That sounds like a bug
