Now that I'm home it is a lot easier to type.
I don't think you need to quit at all. Yes, Foley has become unpopular because he's always been portrayed as immature and unstable. Everything about his personality made him come off as an adolescent. Possibly because you are (not necessarily a bad thing) or were a teenager when you started playing. Nonetheless, he had many character traits that together made him come off as a kid with a gun.
- His gullibility, and vulnerability to being manipulated and/or tricked.
- His emphasized complete lack of experience with members of the opposite sex (or same sex).
- His overemphasis on everything awesome: guns, explosions, destruction, etc
- His lack of accountability and/or responsibility.
- His refusal to heed advice given until he's already passed the point of being helped.
These are some of the common traits attributed to male teenagers. Things many of us can relate to OOC in recent memory and say, "Yeah he's a kid!". At least, I can. A lot of things Foley does seemed funny or cool back in those days, but are tired jokes that I've personally grown out of. A lot of characters probably feel the same way, seeing Foley as very much their inferior because he comes off as a teenager with a rifle.
The fictional-reality here is that Foley represents something incredible and tragic. He is an immortal soldier that has seen and caused more death and destruction than anything you as a player can possibly comprehend. He's experienced extreme emotions on a scale that you and I can't relate to. He's literally died. He's lost limb, parts of his face, entire sections of his body just before dying. He's laid there bleeding out on the ground for hours before finally succumbing to death. He's been through horrifying experiences, and
he remembers all of it.
I think a lot of DUST roleplayers get this part wrong, because you're approaching the character from the perspective of a Call of Duty player, not as a war veteran. You're completely missing/skipping the ugly psychological effects of war. You're not alone in this, as I have yet to see a DUST roleplayer that convincingly portrays somebody who's experienced that life. DUST soldiers are likely be certifiably and irrevocably traumatized and/or psychotic, but not in the way you seem to think. It's not cool or funny. It's horrible.
So, if you want to salvage Foley, I think you need to seriously consider removing his humor and playfulness. Somebody like him isn't likely to be concerned with whether Diana Kim gives him a smooch. He's more likely to be suffering constant nightmares, severely alcoholic, prone to emotional outbursts or antisocial tendencies, or other not-fun personality flaws. Foley doesn't need an audience to laugh at his jokes. Foley needs a therapist.
That's the reality of an immortal soldier.
EDIT: I should also point out that you don't want to drift too far in the "
war is hell, pay attention to me" direction. I don't want to generalize, but most vets I've been friends with are not eager to talk about the shit they've seen. It's more likely that Foley ought to be a quiet and reserved personality more likely to form friendships with people he served with than random capsuleers. Katrina hasn't experienced what he has. Why should he respect her?
"She's just sitting in some pretty office all day giving orders to the knuckledraggers like me to do the REAL work! Stitcher? Pffft, just some egger trying to run his big jaw, he doesn't actually do any fighting like I do!"
Foley could stand to be more dismissive and condescending to capsuleers, because he's been through enough hell to earn his damn respect. Those who won't respect him anyways?... well they're just not worth his damn attention! At least, that's his point of view.
Go watch some more war movies. Pay close attention to the way the soldiers are when they come home, and how they are with each other in the field.
