Okay, using some Borderlands Math to illustrate to you the general picture:
Axton (72) - Legendary Soldier
(1+0.35+0.4+0.3+0.3+0.05) x 2 x (1.05) = 5.04
Maya (72) - Legendary Siren - I’m not using the Leg Cat, though the numbers are higher, because most gun Mayas run Siren
(1+0.3+0.3+0.39) x 2 x (1+0.5) x 1.25 = 7.46
Zer0 (72) - Legendary Killer (not even counting the massive burst damage OOD or Ambush)
(1+0.5+0.2+0.3) x 2 x (1+0.57+0.4+0.3+1) x 1.8 = 23.54
Gaige (72) - Chaotic Evil Nechromancer (understanding that scoring critical hits is difficult for her)
(1+7.5) x 2 x 1.54 = 26.18
Not doing Salvador because NKLO is pretty unpredictable, and with Krieg, PiP messes up crit calculations.
Axton’s advantage is that with the Soldier Com, alot of that DPS, inclusive of indirect skills like Ready and Expertise, are pretty much passive. But on a flipside, Axton also has alot of circumstantial powerful skills - Metal Storm, Onslaught and Battlefront. All Maya needs to do to reach her peak DPS is to phaselock an enemy.
Of course, while I feel the game designers should have been more generous with Axton’s damage skills, it is sufficient even at OP8, provided you use strong guns. But he is not the type of class that can take a mediocre gun and make it amazing like Sal, Krieg and Zer0 can.
don’t sleep on Legendary Soldier Axton yo!
Don’t get me wrong, the Soldier is a really amazing class mod - up there with the Siren as the best Gen 1 mod. But a large reason it is so revered is because Axton doesn’t have a proper pure DPS Legendary mod like Zer0 and Maya do. The Leg Ranger is his ‘DPS’ mod, but by neglecting to give a passive DPS buff (and boosting Ranger instead of Battlefront/Ready), they really gimped its potential.
in Sentry, fair enough it would make your turret much more powerful and go well with the 5 you dump into Battlefront but I dunno… I often call back my turret shortly after deploying to start cooldown again, almost like a kind of super grenade
I know you are still Lvl 50 and stuffs, but Sentry is one of those non-negotiable 5/5 skills UNLESS you are running a pure grenade build (I would still put 5/5 though). As you progress through the higher difficulties of UVHM, you will realise how important your turret is - especially once you grab Double-up. Expertise I would put 1 point if you are using the Soldier - the swap speed is valuable, but not something you absolutely need 10 points for.
