I find icons across most jobs to feel very disorganised and un-instinctive. A lot of them feel like the artwork was done at a much bigger size without consideration of how it looks shrunken down, and there's no pattern to combos or good visual cues of the effects.

It's been a while since I played Scholar, but I remember being specifically annoyed by all the faerie spell icons being slight variations of "faerie in a non-descriptive pose" on the same coloured background, with no visual or colour clues as to what they did. I don't think that much could be blamed on change over time.
