I'm still using it as a decent starting item, the charges feel like actual pots to me now, and I get to carry a ward still w/ 2 additional pots.
I felt w/ the old flask, what was excessive to me was getting away with getting so many items with it.
Ex: Flask, fairy Charm, ward, pots, etc..or like an unlimited sustainable sololane.
It was a ridiculously good start, and I still think it's a good starting item. All it is to me now is alternatives rather than my primary preference.
Doesn't sound like a nerf on the last part, sounds like an abusable bug.
