[2.0] RF Flameblast, suggestions?

So I've never made a character that uses RF before, and there are no guides or builds that I can find that suggest RF and Flameblast for 2.0. I hope I'm not missing some glaring nerf they did or something to make it unusable, hopefully you guys know better than I.

The passive plan:

Now do you guys think it's too focused on getting damage? should I forgo something to make the 12 point investment down to the duelist to get the 2.6% regen? I'm so hesitant to do that since it's so inefficient but I don't know how reliant RF would be on that extra little regen.

Any suggestion for Flameblast links? I was thinking FB + fire pen + ele prolif + spell echo + ???, any suggestions on that? I don't know the best way to get all the ignite chance, does it mostly come from flammability and FB quality?

Thanks in advance!

Hi, for some ideas, lvl 23 purity of fire, shock, elemental weaknes and elemental equilibrium help more then ignite

hi,

no need to get the 2.6 Regen from the duelist just run vitality and you should be fine. also i made some changes to your tree check this out http://tinyurl.com/oyqz8mu. i add some cast speed and more mana/life Regen and hp, since spell echo doesn't work on fb anymore i feel like cast speed is essential now. as for links go fb+fc+conc+aoe however since this is an rf build too idk if you would need conc or aoe,but anyways if you have a 5l you can go fire pen and 6l go inc burn damage or culling strike last link is preference but i like culling strike since it gives cs with quality. this is a mard build but i think it a point more effective as a templar
