Lack behind was about the fact that MangaSushi have a hard time translating/updating weekly manga. I'm still happy to see chapter Pop up but I'm just tired to read people complaining about Snipe or when someone just try to release something that is slow on the update (with MANY chapters behind) when nobody have a "Right" on a manga.
Look on mangadex or search on the internet, for many series you have more than one team translating on tons of manga/manhua/manhwa, at the end of the day people enjoy reading, that all there is to it.
Almost everytime someone tried to translate a series that is behind in chapter or was "forgotten", the team that think they have the "Right" on it complain, (in rare case propose to help and improve the release with those people, just saw it 4 times since I'm on mangadex) or the fan of said team just give harsh criticism without even saying thanks for the work and don't try to understand why they did that. (well, there is troll too)
I already said this line before in many chapters but translation is a gift for those who can't read japanese korean or chinese. I appreciate every work from someone that want to send us a present like that cause I'm not kidding myself with the amount of work it is to just release one chapter people translate on their spare time.
And as I said before, If people complain about "Snipe" while it's illegal to translate manga unofficially, they don't really understand the meaning of translation like it was intended before.
(I'm pretty sure I messed up a lot here with my english)
