Take out burn and rain of fire and get aid self both pretty much useless and not very team pleasing.
Take out two of the TB buffs on build up and put another damage and recharge in FSC (its the reason you go fire manipulation seems a shame not to have it fully slotted).
thePhilosopher Martial Arts/Regen/Fire Scrapper
theRegulator Empathy/Energy/Soul Defender
Total Inertia Ice Blast/Kinetics/Psy Corruptor
Total Inferno Ice Blast/Thermal/Leviathan Corruptor
No!!
Dont take out rain of firee its great for slowing down those pesky enemies 
Get rid of group fly instead aswell as burn for Aid Other/Stimulant and aidself
If you keep rain f fire, be careful about using it in teams. Most of the time it messes stuff up. However it is great solo.
@Unthing ... Mostly on Union.

My Fire/Fire Blaster is currently at level 16. Be aware that the ire/Fire mix is an aggro magent as most of the attacks are AoE. For what their worth these are my observations based on my own experince so far.
If you do get Rain of Fire I would advise you not get it until you ae well into your twenties. Its more of a liability than a help at the lower levels especuially if you are on team.
You will need a fair bit of end reduction in the powers at the early levels as it is an end heavy set. What it wuill be like when you have aslotted Stamina I don't know. You might then be able to respec out some of the end redux slots.
Some really useful advice I received recently is BE PATIENT. Wait until the team attack is underway and the tank/scrapper are well into the thick of things before you blast off. If the tank is good they will keep the aggro despite your attacks or hopefully your attacks will weakewn the bad guys and the scrappers will spalt em before they ge to retaliate on you. This onepiece of advice would have saved me MUCH debt if I had know it from the start of my blasting career.
my first lvl 50 toon was a FIre blaster =P so dont think I know how to use RoF I always ask before I use RoF and I only do it when theres a controller to imob them or in small rooms such as in frostfire and theres a storm using gale to keep them back... however last stragety usually gets me killed o.O but by that time most of them would be already dead
EDIT: if I tooked out Group Fly and burn wouldnt that mean leaving it a bit late? or wouldnt that matter? cuz I'm not a fan of Bonfire used to but since they changed the graphics it looks crappy and why bother taking it when RoP leaves a patch of it any way when you rezz...I suppose I could drop char down to 44 and Fire shield to 47 and Rise of Phoenix to 49 and take Stimulant at 35 with Aid Self at 41 would that be ok? because then I wouldnt have to bother making any major changes 
After my tank i'm planning on leveling a Fire/Fire blaster.
I'm just wondering realy if my choices of powers are ok?
