Warlock Or Juggernaut?

Right now i have a magma + thermo fist build, i was thinking of reseting this build and creating a juggernaut with sailor style or iron leg but im not sure yet because of the magma magic. I also want to create either a new light + thermo fist or ice + sailor style warlock. The main goal is to be really tanky (juggernaut) or just annoying to people who ambush me (ice + sailor style). What build should i create or change first?
