Might as well say you don't understand why people farm in any game period for pixels.
Eh, he's got a point. Farming for farming's sake is boring, and that's exactly what is in BL2. I've put a lot of hours into both games not because I like farming but because I like tinkering around with different builds and weapon combos, fun stuff. Twink out a Lilith in BL1 and set the players to 4 and see if you can survive!
Unrelated gripe: Tiny Tina DLC has been fun so far, but it's clear the developers don't know how to add complex challenges. Everyone should carry around a fire and corrosive weapon, the main game teaches you that. I decided to put slag and electric in my other slots. Fun times when the devs put in the following combinations of enemies:
Resistant to all elemental damage
Resistant to all elemental damage but takes normal damage from corrosive. Has a red bar so that you erroneously think it's weak to fire.
Resistant to all elemental damage but weak to melee attacks. But not if your Krieg or Gaige, your default melee attacks do shit, so you need a bladed weapon.
Resistant to fire.
Resistant to electric.
Weak to corrosive(standard yellow bar guys, just thought I'd throw them in).
And of course, if they aren't any of those guys, weak to fire.
I like Taloo's suggestion of a slag grenade, I honestly had never thought of that. So that frees up the slag weapon slot. But I still need fire, corrosive, explosive, non-elemental, and bladed weapons to cover all the enemies. Oh, and one of the (optional)quests requires an electric weapon. No idea if the quest provides one.
Maintaining that many weapons is just stupid. I mean, I guess you could eschew all weapons except non-elemental and keep Scarlett DLC Rapier around all the time. But that's slow killing unless you play an Anarchy Gaige and a couple shots/pellets will kill anything anyway.
Bleh, this game has a lot of promise and I think they're going the wrong way with it. There's gotta be a better way to create challenging foes.
