First if you are delaying Contagion that much then learn to play. Don't just pop DWT as soon as you can. SMN has always been about planing ahead, that hasn't changed even if there is less of it now.
Never used it once in A8S. Pet only died if I messed up, which might have happened on like 2 or 3 pulls??? Mained SMN all of last expac with decent rankings without caring about speed clears and very good clear times while not killing myself raiding. Look up my achievements before assuming I don't know something. I said RDM utility is better than SMN. RDM utiility is broken, but RDM needs a nerf, not the other way around. Nerf RDM, take a look at balance after that, then consider a slight buff.
BLM has 0 utility. They are the SAM of casters. You will never do as much damage as they do, get over it. As for your comparison to RDM, you are wrong. Don't look at max parses, 95th percentile is a much more accurate depiction in terms of dps numbers. That is the peak of play without taking into account really good proc RNG (which SMNs have low play numbers and will have less of atm), speed kill strats, or derpy stuff where they are being fed balance the whole fight, or AoEing much more than a normal strat would.
