Likely Caster LB and Caster spot in raid balanced parties. It could have melee LB and compete utility/slot-wise with melee DPS, and i would like for it to, but I don't think that's very likely. Its not hard to outshine BLM/SMN in utility given that what they offer mostly defensive (E4E, Virus/Supervirus, Apoc, Raise, weak Physick) benefits but what is most attractive are offensive benefits. There some skill changing and new skills coming, so comparing utility right now vs utility at level 70 might (hopefully) be different.
Haste is a sticky issue. AST has Arrow card and no one really likes it except for BLM due to it accelerating resource depletion and BLM having infinite resources. Self speed buffs are a bit different since MNK and NIN TP costs take into account that they have a Haste effect most of the time. Adding on top of that is still a problem. There are plenty of other options for RDM utility though.
