I have experienced the same difficulty LTx Doesnt support 2hand characters to my knowledge. Give VTank a try. If you use it for looting VTank is very fast at salvage and loot. The setup for a looting profile may be a bit tedious but I think thats what you sacrifice for the speed of its salvaging and looting.
Yes you must have a shield item also, problem in doing so is that the weapon you select for both, ie bludge weapon, is the only weapon you can use. It will not auto switch to, ie acid for ninjas, cuz then it tries to equip both you bludge and acid as the same time.
Vtank is nice that it uses that option of auto switch, but it doesnt have a nav for one, to stay in one spot and you can get dragged.
