I haven't seen the outfit, but I've heard it's bad-ass. Shame that from my experience Raul was pretty useless in a fight; I kept him around just for his funny comments (nice work, Trejo!). Though, to be fair, I never had him use any weapon except for his .44 revolver.
And yes, I was upset when Arcade left me, but it was pretty cool joining him and the Remnants at the battle of Hoover Dam. It's just so sad that Gannon's forced into exile, and the Enclave ends as quickly as it started.
