Some series that are quite slow but would love to see some more of faster releases.
Seikon no Quasar - only 2 chapter released so far, but looks like a great series.
Soul Eater - long gaps between releases, and seem like an interesting story.
Rose Hip Zero - 2 volumes released. also stalled at 5 volumes as well.
Shakugan no Shana - watched the anime and liked it, but the manga seems better in the way its written.
Girls Saurus DX - been a long time since a release and were sparce.
Magikano - slow but quite a worthwhile manga as well
Hunni: Cant exactly release claymore scans if the raws arnt out for them yet. think the groups all caught up now. not much to be done about it
