Seriously though, yeah, it can be annoying to be on the low level side of the equation in that case. It's a good thing DSEs will eventually be replaced with something different entirely.
I personally don't mind it so much, even when I'm the low level character there. I just fly around searching for enemies my level while watching the kill counter rise the the mission eventually complete. Or I'll try to keep up with the high levels and throw in my pathetic little phaser shot here and there to feel like I'm doing something. Either way, I get SP out of the deal :p
