things that need to be fixed from most to least important
1. Stats need to be buffed:
I'm pretty sure the special stats need to mean more. Thus far most of them only effect whatever skill they are related too, they should have effects in addition to that like they previously did when it actually meant something to move a point from one stat to another:
Str- lower initial carry weight, then add more per point of str, then put min STR values on the big guns
Per- without a high perception you're chance to hit with guns should drop off dramatically at long range. ie just because i have 100 in small guns I should not have a 70% chance to hit something out at the edge of my clip plane unless I have an 8+ perception
end- how much does this effect HP gain? doesn't seem to be much... make it more.
CHA- follower limit... people should mod in more followers, make them weaker (fawkes is just way too good im pretty sure the guy can solo deathclaws) then make the number of followers you can have based on your CHA
Int- fine as is (but more speech options as a smart guy would be nice, though everyone has said that)
agi- fine as is
luck- the was always more of a you better keep at least average (5) points here or else kinda thing. somehow it would be nice if critical weapon failures were modded in and if you had a really low luck value you would end up shooting yourself 15% of the time, or your gun would suddenly lose like 75-100% duribility.
2. Super Mutants need fixing:
someone needs to finish the super mutant story line. While its true FO2 had a whole bunch of quest lines that just dead ended, this is ridiculous its like something that almost every NPC will talk to you about but not a one has any answers. they all say "the super mutants are looking for something in the down town ruins". Though no one knows what... mod someone in who knows what... make it a quest to take whatever they are looking for from them. Additionally there need to be some mutants you can talk to aside from fawkes who are completely retarded. one of the bets parts of FO1/2 was being able to outsmart the mutants. Also they are all carrying hunting rifles... wtf... their hands are supposed to be too big for small guns, they should all be strapping big guns which leads me too...
3. Guns:
there aren't enough big guns, tactics had enough... where is the M60 or the SAW
Additionally the hunting rifle needs to suck more, that was only a gun you were to be using early game when it was the best you could find, i found myself using it all the way up until level 17 when I finally decided to get taken to raven rock and plasma weapons where everywhere. the solution to this is nerf the crap out of the hunting rifle and but make it share ammo with the sniper rifle... and just for kicks implement the Gauss rifle because that thing was badass. In general maybe have less classes of ammo so we can actually use some of our favorite guns from time to time... the magnum is utter crap simply because I can't find ammo for the thing.
Maybe I'm just paranoid but I'm pretty sure the hunting rifle actually has better long distance hit chances than the sniper rifle, how the hell does that work?
In short... screw the hunting rifle.
3. Skills:
the repair skill really needs to be worth less. It's like absolutely mandatory you max that one out or at least get it to 80. there are several ways to fix this, either make all things break slower and only have major damage to guns when you get critical luck failures, or put more people who can repair things well (best I've found is the armor caravanner and hes the only one) out there in the wasteland.
Additionally (separate repair issue) the player should be able to repair crap without an exact gun match. the game pretty much forces you to play with 3 guns before the enclave arrival: hunting rifle, assault rifle, combat shotgun. I wanna use em all when I feel like it need mods to make most most pistols repair each other and most rifles repair each other. (and most armor).
then we get to stealth... how freaking useless is sneak even with a stealthboy on people can pick you out w/o much problem, I realize there are a lot of factors that play into this one but come on, I found myself never using this.
You can get several mods which spread out your skill growth over 40 levels, with fixer points per level and more time per level up! 
i once again received enlightenment.
