Not true. This effect is visualized in my character's sheet: My health regen increases when I summon a frenzy totem (but not the minions regen)
Also I tried summon my minions AFTER I activated a totem and the health regen was not visualized either.
Either the buff is not working or the character sheet needs a serious rework.... In any case we need a confirmation from a dev about what is happening here.
Yes it is true. I'm one of the people who made it.
The stat you have pointed out in your character sheet is your own "minion health regen". The stat you are referring to on yourself is your "health regen". The totem grants "health regen" to you and to your minions. It does not grant "minion health regen" to you.
The character sheet is displaying the stats correctly.
The minion's "health regen" stat is not displayed anywhere.
