Fire for TR seems to be quite a bit more efficient especially when coupled with strongarm bracers as the buff stacks for each person in your party using them.

I can do 3 min level 30 rifts with my 3 monks fire TR build currently. I don't play for high progression in GR on my boxing characters only for my mains so it makes it a lot of fun to just speed through stuff for shards and what not.

TR is for sure underrated.
