Well... I think Picaflor is just expressing his feeling, as everyone has one's own emotion towards particular thing.
For me tho, she is this type of person since the beginning of her career, so I'm not really bothered by that. Of course she had a faster schedule in pre-UB era (or probly pre-DR

). Then again, she was considered "slow" back in the old days when ayu was releasing stuff almost every single month. So she's really not that slow now (if ayu only released a few cds per year, I dun even need to hope that hikki will release the same amount lol).
And she's not really a performer, not even an artist. She's a musician who only loves to release thing when she is willing to. We can really think about her in the same way. It's like... yeah probly she was not even doing anything at all about music for a few months before she decided to go on hiatus and wrote 5 new songs for the farewell. Nonetheless, we can't blame her for the lack of production. She's more realistic compared to, let's say ayu or kuu. Those artists are surrounded by staff almost 20-24 hrs every single day. I dun even know if ayu can manage her own life. I'm sure hikki can manage that, but she really wanna feel what a normal person would do in normal daily life. I'm actually happy with her decision because I dun wanna her to live in a protective bubble like ayu does. Everyone's telling her she's right (or maybe OK), but they'll never tell her what's wrong. This is not really healthy.
Also, I have a feeling that hikki's music will have a new direction when she's back. I will wait for that
