@flupser: For what it's worth, I don't care if you snipe us, we sniped it from Heizz in the first place. If you think you did a good job, go for it. We'll keep putting out our chapters too, and the readers will decide in the end which version they prefer. I didn't read yours, so I have no comment on the quality, but otherwise we welcome competition.
The issue with a double-translation is everyone already knows that context is lost going from one language to another, so doing it twice means a lot more can be lost. For people who don't speak either language, they can't help wondering what was left out or how much fudging was done to make it sound good instead of being an accurate translation. If something doesn't sound right or make any sense, is that because the JP->ES failed, or the ES->EN failed?
Regarding how Sansui beat Saiga, remember that in chapter 8 he specifically detected when Saiga used his foresight. It was also stated that Saiga's stats all rose a huge amount. Yes, if we're talking about kendo, a joudan stance is considered to have the weakest defenses. However, considering Saiga's power-ups and his foresight, he can counteract that weakness fairly easily. So, at least how I read it, the main reasons Sansui was able to win was because he could detect when Saiga used his foresight, meaning anything done before he used it couldn't be predicted, plus he had the ability to instantly throw Saiga with only a touch, so he could actually put that theory into practice. If his attack required time or movement, I would presume Saiga would have been able to see it and counter it. As stated, Sansui was simply the worst matchup.
