Trying to change up my build, help?

So this was the first character i had made in POE and actually gotten to end game in a very long time. I picked flametotem mainly due to ease of use but i've found it to not be my taste. I'm trying to figure out the best way to convert my current build into a flameblast build. If someone could look over what i'm currently running and help rewire it as best as possible that would be great!

I'm wanna try to run with discipline/clarity/AA so keeping eldritch battery and my other mana regen nodes is somewhat important

First, unskill every totem node and try to skill as many cast speed and increased area of effect nodes as you can. Though keeping a Decoy totem can be helpful to concentrate mobs in the radius where you cast FB. The faster you can cast FB, the better.

A possible tree could be:

Note that there are more cast speed/icr aoe nodes than I put points into, just to give sort of a direction.
