Currently am using a light sorc for mf and have the gear but still cant mf without dying what is the best class to use to clear chaos and run andy and meph to mf fast and easy?

Yes fast an easy
If you arent very good at playing like you say hammerdin has better survival

If you are dying too much then you are playing too aggressively. Try to be more conservative when you extended into mob packs.

What are you geared with?
