well, personality-wise he strikes me very much as the spear counterpart version of Cammy: they both have the initial amnesia plot, they're both quite quiet and have a soft spot for animals :3
This is the thing, if Abel was always as he is now I don't think I would've even been all that fussed. For my personal tastes he kind of blends into the background and there's nothing wrong with that: he's intended for a different audience and I don't actually have an issue with that or the people who like his look
The only reason poor Abel insights my ire is because his original design was an extreme rarity: a capcom grappler I actually liked the look of. Being reminded of this unfulfilled desire just kind of aggravated this festering annoyance I've had since way back: I'm more into hard reads, mind-games and simple damage so grappler movesets actually resonate pretty well with how I work as a fighter, but I really, really, really, really, really dislike the characters they keep putting into that category. It's so incredibly rare to see someone l actually would like to play with the movesets I enjoy. My fighting game career is pretty much just me making do with whatever moveset I get stuck with. I've tried playing characters i dislike to access movesets i actually enjoy but it just makes me hate the game and inevitably either quit or switch back
So now every time I look at Abel, I don't see him but rather what he could've been.
As for fulfilling roles within the SF4 newcomers, It looks like in the original sketches that Rufus was originally meant to be 'the guy' with his king cobra design. I can't speak for his attractiveness within the particular aesthetics though as I think peeps like Remy or Vega are more in line with what I think of whem people talk about boys and eye-candy
