Is it possible, or worth while to solo with a warlock?
I think that your question is possibly too narrow in scope. It should be "Is it worth while to solo?", and then the answer would be (in my humble opinion) "NO!". Soloing from 1-70 will not give you the skills to work with others in end0game scenarios. Likewise, PvP (battlegrounds and Arena) are group things, where you have to work with others. Deliberately going off by yourself and avoiding group dynamics will never make you a better player, let alone learn your class role in instances, battlegrounds, and/or Arena.
