IMO similar to Brawn Sal, the whole LBT tree needs a buff. Currently, the whole Elemental tree is very toothless at OP8. Most people simply go down it to pick up WDT (which is pretty overrated IMO) and IO (which is nice when boosted by a Catalyst or Technophile).
However, I would like to believe the core skills of the tree is really the synergy between EB, EE and WDT. This combination works pretty well at OP0. However, the primary advantage of EB (which is because it remultiplies with slag) works against it at OP8 due to the increased damage reduction. Even if it sparks from a relatively powerful DOT (like a grenade or S&A), it struggles to kill fleshier bandits like Nomads or Bruisers. Which shouldn’t be the case. By contrast, Krieg’s burn dots are fairly powerful, and only require a 5 point investment to melt fleshy Bandits. And his dots are largely a means to an end (stacking EE or healing). Given EB’s dots can require at least a 15 point investment, it honestly should be able to kill badass enemies (with EE active). I mean, Cloudkill shreds Loaders without much difficulty and is only a 1 point investment!
More Pep: Electrocute chance increased to 7% rank (Since Flicker is 6% for all elements). Other elements 5% per rank
Shock and Aagghh: According to @Chuck80, the base DOT value is 20-25. This should be increased to 65 in line with the top-tier shock grenades. That said, the actual nova damage is pretty good right now.
Evil Enchantress: Increase Dot Damage to 15% per level. I know this is pretty extreme, but honestly this is the easiest way to make EB effective (on kill) and counteract the massive damage reduction at OP8. Short of massively buffing WDT which I feel could be too OP on shock guns like the Twister.
Electrical Burn: Increase chance to 7% per level.
WDT: Increase Shock Damage to 4% per level. I think making it 6% would be too ridiculous. That said WDT is pretty overrated. One should realise that while the skill is ‘multiplicative’ to gun damage, it is not a true multiplicative like DM, Ambush or Reaper. It is still additive to all elemental damage, and simply occupies a different side of the damage eqn. If Athena had WDT, it would be completely insignificant to Maelstrom.
Interspersed Outburst: Yeah, I know this skill is pretty decent at 10 points. That said, Gaige has no real slagging/swapping skils barring IO and even at 10 points, it can be pretty unreliable if you are not at full stacks. And if you are trying to keep up your kill skills like EE, waiting 10s so you can slag people can be very counterproductive (esp when it still fails to slag at 5 points). Honestly, I feel that IO should have a guaranteed slag chance at 5 stacks at 5 points, and less stacks should be required to slag people beyond that. Hence, I feel it should be buffed to 4% per stack/ level. The slagsplosion damage is okay.
Other Skills:
Potent as Pony: Increase DT’s health by 4% per level. Gaige health bonus is okay.
Made of Sterner Stuff: Damage Reduction for DT and Gaige increased to 3% per level.
Smaller, Lighter, Faster: Increase Reload speed by 7% per level.
Typecast Iconoclast: Chance to get extra stack increased to 10% per level. I don’t think a guaranteed chance to get 2 stacks at 10 points would be too OP or anything. Also may make With Claws viable without pre-stacking.
