in real fact, studio anime yang outsource animator korea selalunya hanya mampu manghasilkan anime yang crappy. Great example is from Studio Pierrot that are producing Bleach and Naruto.

And yeah, you tend to forgot Atlus and Falcom.

crappy. real bad one. only faggots watch this shit.

Not true. It is just studio with lots of outsourced korean animator usually did not perform well in animation side.  Story-wise they are ok because mostly the anime they are producing are adapted from manga or video games or novels.
Now here, I am not telling that all koreans are bad animators, it is just that those studios (Pierrot, some sub-dept in Sunrise and JC Staff) unfortunately hired bunch of low quality outsourced korean animators.

Some of your points are valid but some are not. You must be new to anime and this kind of stuff.
1. True that anime will boost manga sales. But in case of Naruto and Bleach anime which comes from the same studio, no. Both manga was quite popular even before the anime are produced. The anime were produced to gather more fans and boost sub-product sales.

2. Dragonball anime quality far superior than Bleach and Naruto. Toei Animation is always winning Studio Pierrot anytime.

3. As I said, not all Korean animators are worse. Sunrise successfully hired good quality of Korean animators. Please watch Gundam Seed series and latter series, Gintama series, and Soukyuu no Fafner. Compare those said anime made by Sunrise to the most anime made by Pierrot. While I am liking some of Pierrot's works like Gensomaden Saiyuuki and some others, I always uncomfortable of the way they deliver their anime. Also to note you, story-wise without referring any adaptation from manga, Pierrot's filler episodes are awful, all of them.

4. Even for a long running manga to adapt into a long running anime show, they need to prioritize on the animation quality. Dragon Ball's quality never drop until now. Just look at Flame of Recca, Bleach and Naruto for example, Pierrot are not able to maintain those anime quality in a stable manner.

5. I understand the budget constraints occuring in some animation studios, but that is not a major problem here. Why the hell did a studio even take a long running animation project if they did not have their budget allocated in the first place?

Conclusion: The thread topic has been derailed. Ohwai.
