BLM doesn't have raise by virtue of having infinite MP. Has nothing to do with DPS regardless of what devs say.

Pretty sure SMN has better overall mobility given you only really hard cast 4 spells. Miasma, Ruin 1/3, and Resurrect and occasionally Outburst. The rest are instant or oGCD. SMN lacks a dash/teleport since it is free to move at all times.

For RDM to get Dualcast they need to hardcast a spell. And a majority of their rotation is a 1-2 combo of hardcasting a spell then using their DC proc on another spell or something else.

IMO BLM and RDM have warps or gap closers for the fact they have less mobility overall. You can argue that BLM mobility is rather good if you use AM effectively and instead of using LL as your damage CD you use it as a movement option.

On a separate note I disagree with Red Mage being the most unwelcome. Blue Mage takes the cake for that. Mainly because level cap and poor design decisions.
