It's really not a big deal. Only to min/maxers. In the real world, good teamwork in this game overcomes the loss of one persons "supposed" 7% dps loss of which 7% would only be in a perfect world where you could have it at 100% uptime. In reality most SMNs may see a 2-3% loss which would add, oh I donno, 4 seconds to the average boss fight?

Sorry but I see no reason to complain here even as a SMN main. I feel our strength comes in being able to wreck multiple targets so losing a little dps on single target fights is nothing. Take Caduceus as an example. Being able to DoT both snakes after the split is something that no other job can really do and helps make the fight a little bit easier.
