Also do note that B-tier isn't necessarily bad per se, Jobs in B tier just aren't necessarily as good as A or S tier jobs for a number of reasons ranging from lack of CC, being too easily countered, or lacking reliable on demand burst. (Example being : Wildfire, Between the eyes, Sidewinder, require a setup and can be dealt with easily by a capable player, or a cleanse. Where as there is no counter to a monk doing their burst rotation properly aside from healing through it, or hoping the monk didn't pop fetter ward.)
