I am currently making a skellimancer, and it is doing fine in p8 Normal. As soon as I get another 3 to 4 skellies, I can clear the Chaos Sanctuary, and then on to Act 5. This is all being done with virtually no difficulty, and I don't believe I have died since Act 1. Nightmare will be harder, but I should be able to run Meph, albeit with very slow runs. I would advise one of these for your next char, since they are able to run the Pits quite easily, I am told. However, your choice of meteorb is a good one, also.
