Recommend a primary?

I really want to make a /Fire blaster but i have no idea what primary to pick, any suggestions?

I'm very much enjoying my Elec/Fire/Ice though I suspect he'll need a large overhaul come I24. Massive amount of AoE carnage most of it at arms length.

What about /Fire draws your attention, it may provide a clue as to which primary you may enjoy most.

With /fire, you want a primary that's great in melee. The best are probably fire, rad, and elec, depending on your preference. I'd lean towards rad, because it's very effective, while also being about 1000 times more rare than fire/.

Water/Fire hands down.

Fire/Fire is pretty beast...

However I could see water and rad working pretty well. Rad is the slowest though if that is something that bothers you.

You never go wrong with Ice/

Okay, so here is the skinny on Fire Manipulation:
-Awesome PBAoE Damage (damage radiating around you, usually best for melee) in the form of Fire Sword Circle, Blazing Aura, and Burn.
-A solid Single Target Immobilize with comparatively solid damage in Ring of Fire.
-A solid Single Target Melee Attack with Fire Sword.
-Build up to boost your damage like a boss, and Consume to help keep your endurance up.
-A stinker of a PBAoE power in Combustion which has too long of an animation time and a very delayed DoT. Skip this one.
-An occasionally useful additional damage aura at level 38: Hot Feet. This power stacks quite well with Blazing Aura, and has a -Speed component that would be extremely helpful if it didn't also cause enemies to scatter away from you.
-Absolutely no damage mitigation other than Hot Feet and a single Immobilize, which won't even prevent enemies from taking a swing at you.

So how do you play a /Fire character?
-Easy. You use those powers up close and personal.
-That's also very dangerous, because Melee is where you'll be using your awesome attacks...And Melee is where most enemies are able to hit YOU the hardest.
-Playing a melee-oriented blaster also makes some powers (ranged cones) more difficult to use to their full effect.

So what kind of Primary works best with an PBAoE-oriented secondary like Fire Manipulation?
-Sets that don't have a lot of cones.
-Sets that also have a lot AoE damage which can be added to your close-up-kill-everything arsenal.
-POSSIBLY sets that wouldn't cause undo amounts of redraw (that's a personal opinion, and while I think it's worth mentioning, I don't want you to broadcast it as a hard and fast rule).

What does the above eliminate?
- Assault Rifle (best uses at a distance), Sonic Blast (best used at a distance), Beam Rifle (no PBAoE), Psychic Blast (Only a PBAoE Nuke), Dark Blast (All of its AoE is in Cone or Nuke form).
-POSSIBLY Archery and Dual Pistols (due to redraw) and Ice Blast (I love Ice Storm and Blizzard, but it isn't the biggest contender, here).

What does that LEAVE?
-Water Blast: High AoE damage, a small self-heal, mitigation via Knockback and a nice Nuke which a high recharge build can have you firing off every 45 seconds to destroy or heavily damage an entire mob at once. It has one skippable cone, and all of its other powers work very well in melee.

-Fire Blast: The classic combo. It has no mitigation, which means you'll die. A lot. It also has the strongest single target damage of all blast sets, and all of its powers (barring Fire Breath) work very well in melee.

-Radiation Blast: Two solid AoE attacks (one being a PbAoE), a sweet ST Blast with a stun component, and a nice PBAoE Nuke. This isn't the classic Fire/Fire combo, but it works nicely and has just a touch of mitigation on top of the energy damage type.

-Electrical Blast: Two moderate DoT attacks which work very well in melee, plus a hold and an extra unkillable pet which tosses out damage all on its own (and gives a hefty defiance boost at the same time, something like 40%) as well as a very cool looking ranged AoE nuke which can also floor enemy endurance. It's an interesting combination, and the right high-recharge, high-damage build can make it a powerhouse. Now take the knife away from my neck, @Alisha Shatogi.

-Energy Blast: "Merely" solid damage paired with a lot of knockback doesn't make this the "Ultimate" combination, but throwing the Overwhelming Force proc into either Energy Torrent or Explosive Blast (I suggest Explosive Blast) will turn the knockback into knockDOWN, meaning that enemies will be knocked onto their backs right where you want them to be, ready for AoE evisceration. This combo can actually have a whole lot of survivability.

-Honorable mention goes to Archery, which has an awesome mini-nuke (Rain of Arrows) which is great for softening up enemies. Pair it with the overwhelming Force proc in Explosive arrow to knock enemies down as guaranteed mitigation, then hop into melee for further murder and/or mayhem.

-Honorable mention goes to Dual Pistols, which has some solid AoE and a cool Nuke that is up very often and works best in the middle of a mob.

Those are your OPTIONS. What -I- would pick would be either Fire Blast (for raw damage!) or Water Blast (for the most AoE damage additional survivability!)

If I wasn't locking myself out of repeating sets (yet), I would've made my /Fire Blaster a Water Blaster. If you're not purchasing water blast...WHY THE HECK NOT...or rather, Rad or Elec would be my suggestion.
