So you sub WAR i'm guessing, since RDM has no native access to Sanguine Blade. Any time Requiscat would have a use, a MNK with Formless Strikes would have it dead before you got TP ready, not to mention the fact that many other jobs also have access to this weaponskill. Yes the latest update helped RDM considerably, but it also helped many other jobs (some more then others, hi2u Rudra's), but I'll concede that RDM has moved up, before the update I would say that RDM was considerably worse then WHM for melee DD. However, club WS didn't get as much of a boost as sword WS did so now RDM is comfortably leading WHM and GEO, but still lags far behind most other jobs. Not that I even want RDM to be a prime DD mind you, I simply want RDM melee to be an accepted option. I would love for there to be a reason for RDM to be on the front lines other then direct damage.

Not sure how you are getting those WS numbers on anything stronger then trash mobs. Guessing you were fully buffed by at least a BRD, meaning you were in the main party taking up that slot that you say SMNs have no right to. Also in order to make that SC you need to rely on another player to open for you, not that that is hard but other jobs can make their own skillchains (hello mr.BLU).

Your final point is mostly irrelevant since their long buff duration allows SMN to maintain several buffs easily, though admittedly it makes it hard to do both enfeebling and buffing, it does not however hinder their DPS significantly. The only time this might be an issue is when fighting a mob that strips all buffs, but even then not really because it would take a RDM quite some time to rebuff the party anyway. This is also ignoring Avatar's Favor which can supply an additional AOE Temper, Refresh, or other buffs that RDM does not even have access to and is also immune to dispel to boot.
