I know I have been mentioned but here is my build
http://bl2skills.com/siren.html#415001400015155105214550510501
I use
2 Pimps, fire and corrosive
1 Bekah for when either I run low on pimp ammo or certain times where it just does better than the pimp
1 Twister for enemies that are in my face where its hard to pimp and too close for bekah split.
Blockade, Legendary Siren, Bone, and Quasar
I have a few backups, sandhawk for raiding, hail and kittens, grog for raiding, norfleet for hyperious, and a few other items I like to have around. Bee shield for bosses and raiding, leg cat and trickster com as well.
I first made my build right when the second UVHM cap came out and I was sick of always respecing, so I wanted the One Build to rule them all (not the best, just something that was good enough for everything)
I made it so I could wear all 4 legendary com’s and have points in all those skills, I called it a kitchen sink build at the time. Since then I’ve moved a few points around. I dropped the one point in helios because I just never found a reason to really wear the Binder. More recently I moved one point to cloud kill.
But with this build I can be DPS focused, Nurse focused, I can raid, I can solo, etc…
But not only can I do a lot without pausing to swap everything around. WEP is a good example that map has armor, heavy shields with stalkers, flesh, fire resistant flesh, pretty much everything you can run into you do in that map. A lot of builds have a grog to heal, a second wind gun, one primary DPS gun, and one more all purpose gun. With a set up like that you can’t match elements without pausing the game. With my set up I have everything I need. I can swap my bone to match a most common enemy type but I also don’t need the bone for DPS.
So I think its a smart build because it uses skill points to free up weapon and gear slots, life tap and healing allows me to not need moxxi guns and a chain lighting, Immolate and solid guns means I don’t need a FFYL gun. Now I have 4 weapons slots that all can do a different thing and be ready for everything. I have have a quasar that can be a life saver but also makes skills like chain reaction and cloud kill better.
Then I take it to the next level by having 4 guns with heavy Chain Reaction synergy, bekah and pimp have bullet split, twister and bekah have penetration. Pimp also gets reaper on splash. All 4 guns also have great Restoration synergy in 2 ways. One they all can get my friends past healthgate in a single hit, but also I can hit an enemy and heal an ally with a single shot with all 4 guns (pimp 5 pellet split, bekah and twister penetration).
So it for me is about, synergy with skills, preparing for all situations, and being able to hop from solo to co-op, raiding, mobbing, anything. There are 2 raids I respec for still solo, but not co-op.
