Getting to the point where you can solo Deadmines is a good thing. Even though the greens and blues you will collect are below your needs, they are probably good for your alt or even for disenchanting. I needed items to give to my enchanter, so instead of sharing with a group, I went alone.
As long as I paid attention and watched the pulls, soloing with my 36 Druid wasn't really that hard.
