Stand Still Stay Silent. Has a very slow paced prologue however. Also nice because it has an stupidly good update schedule (4-5 pages a week) with extremely good art. Pic related
Order of the Stick if you can get past the shitty dnd jokes of the first chapter. It only keeps getting better. However, it hs an inconsistent update schedule and hiatus every once in a while
BACK, stumbles a bit in the middle though, but it really picks up afterwards. Consistent update every wednesday, usually 2 to 4 pages. Its a somewhat combat focused, akin to a western shonen.
