Is there a reason to play Normal after unlocking TVHM?

[DMZ]

I only own the base game and beat it with Zero. Afterwhich I went to start a new game with Salvador. Eventually I went to put in all the shift keys the sticky topic listed and remembered I had a code for the Torque DLC from a Facebook giveaway long ago.

So I played the DLC with Zero and realized that I had mostly outleveled the content. Most quest were trivial. So is there anything in Normal besides those level 50-only quest I should play for? Is there even anything on Normal worth doing after hitting 50?

Keep in mind I'm a completionist, but if all my rewards on Normal will be at the level 30 range and basically trash to me I'm fine going to the next difficulty. I just need to know if I'd miss anything if I moved on from Normal at this point.

also farming for sherrifs badge is kinda tedious because she wont come off the roof until you kill the marshals. Here is how you can get up on the roof next to her without nade jumping. https://www.youtube.com/watch?feature=player_detailpage&v=dLaZL3Cudg0#t=135

Usage and Description
Moxxi's Endowment can be useful for players wishing to level up faster. However, the percentage increase in experience gained scales with the relic's level thus mid- to late-game players must balance the need for extra EXP with the loss of other stat buffs that other relics may provide.
