Taken the best bits from what I have seen on the forums at this point and reworked the skill tree.
Result is super tanky and gear independent flame totem marauder. Easy to switch to MF for low maps farming.

Gem setup: Flame Totem : Iron Will : LMP : Chaos Damage : Faster Casting
Will be changing to GMP when it's levelled. There are other setups that also work fine but this is working for me. Getting heaps of DPS from Iron Will due to all the STR on the tree.
Update: lacking INT in tree so that makes IIR limited if you want higher DPS.
23.09.14 Update can farm Dom with 200+ IIR but it was a long slog to get there. Need those IIR rings and can boost it even more.
