Here's my rather standard R6 Fire guide for Patch 2.3. It's basically an improved Version of the Season 3 Build, you'll find all things in the Video Guide!
I'm not 100% sure on where the Build stands in competition, but i do believe it will be very close to the generator builds out there. I love the mobility of this setup and i will probably never really give up on it!
Cleared G66 on the second attempt, failed the first g67 by 10s because there was no power pylon to be found. It will probably be strong enough to clear even G70 with a very good rift, maybe higher? Time will tell!
Never use Channeling Pylons
Fight Close to your Templar
Keep an eye on your Spirit and Shenlongs buff
Try to kill blue elites!
good Luck and have Fun with it, i do like the spec!
