And I havent been able to solo any of the raid bosses yet. I am trying to get my Salvador over-levelled and go back to normal difficulty and beat some of them in the DLC. Just uses up your eridium too fast if you keep dying against them.
Really fun game though, I agree. I probably have more hours into this game than any other I have played.
Do you have the Torgue DLC? All you need for Salvador to wreck most anything is a Double Penetrating Unkempt Herald for your main hand, and then a slag Rubi for the offhand (and a decent skill layout). The DPUH does insane damage, especially on slagged targets, and with that insane damage, when you're Gunzerking, with Rubi in the offhand, you'll get insane healing.
