The Salarian Architect, Yes This Guy

his passive tree has a similar debuff as the other salarian you like, something like 30%. With ammo I feel like it kills quicker than the other sentenals, although the numbers prolly don't back it up. His passive skills are different and feel strong. This is defleshing by the way.

i really like this character, one of my new favourites
incineration is great for shor , mid and long range combat and tech combos, shield to protect you and teammates when hacking or de/activating, and the robot to provide cover fire or just attack enmies and cover everyone

It's not my build per se, but my buddy Collector Adept's. SSG Orbino runs his in a similar fashion as well I think:

Step one, don't spec into barricade. In doing so he feels more like the "ranged tech caster" that's reminiscent of the old ME3MP archetypes. I'm sure one of you will find a sick barricade build but so far there's more value in VI and Incinerate + passives.

Remnant VI: 4-Recharge Speed. Because he does die alot, so why not bring him back sooner. The repairs evo still falters against heavy aggro.
                  5-Beam Damage. Mostly same reasons as choice on rank 4.
                  6-Electric Beam. The bonus against shields is ok, but the real value is in the bonus priming. Allows for immediate incinerate tech
                                          combo, then re priming with another ammo type from your weapon and by that time things are either already
                                          dead or ready to be hit again with incinerate or detonated by teammates,etc. 


Incinerate: 4-Radius
                5-Anti Armor (though I haven't played with the other evo here, might be good)                 
                6-Detonator. Must have. The gateway power to making the kit sing, being able to self detonate wth VI in addition to ammo types is 
                                  kinda the whole point of this build.



Offensive Tech: 4-Combo Detonation
                      5- Anti Armor (again open to some experimentation, but armored things are annoying so...)
                      6-Elemental Tech. This one I think is open to some play, depending on the gun you use, etc but for this build, Elemental Tech.


                        
Support Systems: 4-Tech Radius
                         5-Advanced Construction. Mostly b/c Revive thing seems too situational on other evo
                         6-Shield Reset. Talked to buddies, and they're still testing the dmg debuff and how much value it gives. Might be good.



I think he's meant to deal ranged damage, both with weapons and powers, as he is still squishy. (Hence a lot of the initial whining about him here and elsewhere). I don't have a PAW but I've seen it used to tremendous effect, both in straight damage and in ammo type application for this guy. If you use a mid/close range gun, just keep moving is the best tip I can offer. With your game sense, keeping him alive shouldn't be a problem, Megabeast. 

Not even sure this is the best build, but it's worked for me and my buddies. Hope it helps.
                    
                                                                       

Or you can not worry about priming and comboing for fuck all damage and just slap a Vanquisher on him and call it a day. 

I'll answer that with another question:

Why release a product where all the exciting "EXPLOSIONS" take effort and summarily not rewarded the same if not greater as point and click with a mouse?

I'm anticipating your argument will be "If you find it fun, do it" or some derivative, and that's fine. Believe me, I'm fine with other peoples methods of fun. 

But I'm terribly bored with this game where my options are "Sally Salarian's Point and Click Adventure" and "Mongo Mongoloid's Melee Mashstravaganza".

I tried the priming/detonater aspect. It absolutely blows and feels so unrewarding when it should feel like fun and exciting. Hell I went for the Krogan Engineer with the attempt to make it a fire goddess and ragequit that process 5 levels in because it was awful and the contribution I was giving my team so not worth the effort. Their damage for their detonations was the same of mine- a splash of piss across the bow.

So pardon me whenever my eyes roll out of their sockets when someone says of a class "No, see, their value is their priming and detonating!" You probably could make a better argument saying they are playing cannon fodder.

Haven't played in two weeks. I'm just keeping tabs to see if anything major rolls in.

Seem to be guaranteed fast Golds with the Architect.  Picked him up again using this build first tried last week and so far consistent results. 

He is played aggressively into close range.  Open with double Incinerate.  The VI is but a distraction

this character is amazing

you level up to max the relict robot and select to add the missile, set enemies on fire with incineration and then the robot shoots the missiles to the enemies and there is a spactacular tech fire explosion, it's a blast, really awesome!
