The Flakker is an extremely polarizing Gun, there are people who hate it, and people who are willing to make sup par threats towards others for hating it, so after a conversation a while ago I tried the thing out once again but not without taking multiple factors into account:
1: Remove all damage bonuses to leave none of my favorite Shotguns at an advantage (Viral Marketer and Flayer BTW).
2: It’s best damage comes from being in mid range so if I face lunging or jumping enemies I’m in a smidge of trouble.
3: Without Weapon Swap speed bonuses the swap glitch that made it amazing (to me) in BL2 is impossible so the only reason I liked it in 2 is gone while I play as Wilhelm.
4: It’s fire rate is crap but using the swap bug to bypass that would not be fair so I won’t.
5: Bullet Velocity boosts destroy it’s usefulness so no Skills sans Wolf & Saint.
And in my attempts on using it in areas like Custer 00773 Pandora and Triton Flats I found myself doing better damage with the Viral Marketer than the Flakker, the Flayer was in a whole league above the latter. I tried against the Giant Kraggon in Serenity’s Waste but it did crap.
After trying I realized something, I have always disliked Borderlands guns that have awkward ranged abilities. I never liked the UK Harold and Interfacer in BL2 just like how I never like the Flakker in either game, all because they only really excelled in damage in only one range: medium. If I face an enemy that can clear distances in one leap I am forced to swap weapons all because they can’t do much up close (don’t tell me I’m playing wrong and I haven’t tried enough. I. Have. Tried. To make them work. They don’t do anything for me).
I have looked online for strategies on it to find that the only videos on it I found were using the swap bug (Jack), or Broken builds (Athena’s Maelstrom and Claptrap being Claptrap). I’ve seen someone in BL2 dual wield Flakkers as Sal fighting OP8 Jacques and it took longer than using two Tidal Wave Shotguns.
With no progress by myself I gave up, if I do need “special training” to use it properly I’ll pass since I’m not going to bother with a gun I don’t enjoy and if it does have better DPS than the Flayer I don’t see it because from my experience it’s vice versa. Hell the Viral Marketer has better DPS from what I’ve seen.
So I end with this, just because other people can use it, doesn’t mean everyone can. I respect people who like it (as long as they show a modicum of respect towards me back) but IMO (In My Opinion) it’s my least favorite (I’m kind of a Jerk) Shotgun in TPS because it’s the only Unique/Legendary Shotgun I can’t kill squat with.
Literally, I can’t even kill Squat with it.
