Arcanist (and all the other classes tbh) needed to go in 2.0. It just sucks that the experimental '2 jobs from 1 class' concept fell onto my favorite job in the entire series but what can I do.
At this point, however, it is clear that both SMN and SCH need a complete overhaul. We'll never have two completely functional jobs as long as they remain enchained to Arcanist.
