"elementalist" build?

looks like an interresting build, flamethrower for close enemies, cryo for farther ones. I would go with a biotic power like lance or throw as a detonator (sentiel build) or I could even go with Concusive shot. You could even use Charge if you want to keep your enemies closer to you. You could also use the explorer profile, it gives interresting bonuses

Wasn't aware of that, will just have to alternate them with a detonator.

My builds so far :

- Vanguard/Adept : Biotic Charge, Lance, Backlash / Remnant VI, Throw, Annihilation
- Engineer : Cryo Beam, Overload, Incinerate
- Infiltrator : Turbocharge, Tactical Cloak, Concussive Shot
- Adept : Singularity, Lance, Tactical Cloak
- Engineer : Barricade, Remnant VI, Incinerate
- Sentinel : Energy Drain, Annihilation, Throw
- Pure Sniper  : Turbocharge, Sniper Rifles, Combat Fitness

Engineer profile got better Tech damage and power recharge overall as Sentinel but you decide if you go more defensive with the Sentinel or more offensive with Engineer.
My engineer used : Cryo Beam, Overload and Incinerate but this is for high range fight not semi close.
You can handle any situation with this build.

For the semi close range you better go with the Sentinel build you got to sacrifice damage over defense, and Reegar is the Perfect choice of weapon. Better armor is the Heleus Defender Armor, you can buy materials on Aya and aboard the Tempest i think this is slightly better armor than the Angaraan Armor.
