Mamamoo isn't high tier? What are you smoking and can I have some? Mamamoo is above RV at #3 GG of the 3rd gen
Wendy alone sells as much as Mamamoo as an entire group, so...
... but I've had enough of this constant (ab)using of Mamamoo by some RV closet antis here to shade and diss RV all the time, a small group of people have been doing this throughout the months since last year, and frankly it's getting tiresome.
If you feel Mamamoo surpasses RV, feel free to do so, but at the least don't try to diss RV all the time. I have a different opinion, so agree to disagree and all that.
