gear wise buddy i find this the easiest way to gear up get hold of legs quickly efficiently.
Use this
profile i chose to do act 4bounties as it rewards all bounties which gives you a shot at T2 bounties which i think are the hardest to get but most useful. Now once you have something around 400rift tokens switch to a rift farmer all of them are quite good but anyone that will continue to clear the rift after the boss is dead is the best amount of legs.
now give it a solid day to do one then the other profile. at the end of the second day or even during keep an eye out for sets and just wear em once you have at least one set go up to t3 and double check your weapons. barb 2 1handers are cheap and dirty way to kill especially with crit gems.
Once your done here clearing through t3 quickly start looking for +fire dmg anything.. seems to be top of the element dmg's atm. Then try comboing your set with a 2nd set with +fire. For eg earthquake set gloves/pants/shoulders with ik's helm chest belt with
ring of royal grandeur (A1 bounty). Should be able to get sufficientfire dmg somewhere around 60% then you can try going up in Torment.
