To complement damage, fire armour, no arguments. The next alternative would probably be elec, followed by dark. Non granite stone would probably follow, with SR and Invun bottom of the pack (SR just higher than invun).
For survivability, Granite Armour is the best (but will give you the worst damage).
Otherwise, it simply depends on who you are teaming with. Invun and Dark shine in teams due to AoE effects (def buff and mezzing). Elec is great if you can get support.
What's fire melee best with on a brute? in terms of survivability and complimenting the inevitably mahoosive damage i will be doing. ^^
