I've talked about this a lot, honestly. I think that it would have been a vastly better fit for Dex to be the leader of Ultor down in hell, since it would have given him a proper redemption, not to mention the treatment he received in general in GOOH isn't even really worthwhile for people who wanted to kill him. I've killed him so many times already, and he is literally my favorite character. And I didn't even think it was worth it to kill him. The only thing that made him "Dex" was his hat. Why didn't he have a unique body? Why did Vogel, who came so far in Ultor only to fail, get a body and back on top, when Dex, who also did underhanded things to get on top AND got fucked over, is forced to be a husk?
I get that this is just a standalone expansion and that there are reasons they didn't expand upon Dex's storyline, but in this case, they should have either put more effort into Dex (and maybe foregone the "old timey baddies" like Vlad and such, and instead worked on making old homies homies again) or not included him at all. Because what they gave really isn't anything at all. The first time you kill him, you hear him say some insulting lines, then you shoot him a few times, and he's dead. He never gets any stronger, but his baddies do. The most fun I have with Dex is grabbing him as a meat shield and running behind buildings so I can hear the various lines he has. And even then, they serve to make him that much more one-dimensional.
I just vastly would have preferred a redemption arc for him, since outside of leaving the Saints to pursue his own desires, then turning on the protagonist out of both self-defense AND trying to do what he believed was the right thing to do (the first part is more my interpretation, and the second is rather obvious), he never pulled what Vogel pulled. Vogel was letting the Saints take out all the other gangs before sending in his own Masako to try and wipe them out. Dex was essentially pulling a Julius, but in the end he also failed. And I think in the end, with Dex in hell (WHERE IS JULIUS THOUGH) and Julius already being punished (but not really because he isn't even in hell and the simulation isn't even really him), of anyone who should be trying to make amends and would make for a well-redeemed homie, Dex fits better for the role Vogel filled.
That said, I can understand Vogel in the role well and I think he fit it just fine, but I would have personally preferred it if Dex were the one in that role. I could also get up about Troy being a husk for an activity only without getting a chance to be a homie either, but I won't.
I also know this probably sounds like the inane ramblings of a Dex fan who is waving her hand over the really bad stuff Dex did, but trust me, I am aware that he isn't a good guy. I just want to find ways that he could be redeemed, since the boss has managed to forgive a lot of people who did them wrong, and while Dex was one of the worst, I don't think it's impossible for him to be forgiven. Otherwise you'd think all those simulations of old enemies would be summoned by the boss and killed over and over until they got bored. But maybe that's just me.
