She can go on as many breaks as she wants, the issue is she doesn't communitcate. Ever. People are far more tolerant of Ina, for example, because she actually keeps people in the loop. We know Ina is sick, we know Ina has to do work for her birthday in Japan, etc. Gura never says anything.
No one in their line of business has a shift in content frequency as big as Gura's and just never properly addresses it. If frequent periods of inactivity are the new norm for the forseeable future, then come out and say it. Don't pussy around the issue, and only show up when people get antsy. It just feels like teasing the fanbase with shit like "Fish is back!" and then radio silence. Cover and Gura are doing this to themselves.
