No, I don't main SMN, but I did clear UCOB and UWU with it. I don't think you can have raise and do competitive dps with the way things are balanced currently and I'd rather have the dps if my group's caster wants to switch roles with me. I don't think Raise is in any shape or form core of the SMN or RDM identity and taking it out of the dps balancing picture would make SMN and RDM dps more competitive.
Healers would still use Raise. You can't Swift Cast items and nobody wants to sit through 8 second hardcasts if they don't have to. With a 10 minute cooldown you would quickly run out of item raises with multiple deaths and would have to use regular ones. But how often do you really see healers hardcast Raises anyway? Almost never, so they would still use their Swift Raises as normal.
