No more so than you do as, say, a fighter with "universally low stats." There are some people who think any fighter with a 14 Strength would necessarily "suck." I'm not one of those people.
What does a fighter with 14 strength
do?
I mean, he's not hitting things (well), he's not dealing damage (much), and I doubt if he's the party face... I understand that you can still roleplay with low stats since there's nothing stopping you from saying "Thog smash talky man for hurting puppy" but when it comes to the actual smashing, it seems like there's going to be a problem.
Again, I disagree. I don't consider 15, 14, 14, 10, 9, 8 to be "really screwed" stats; I've played lots of characters with stats like that, and haven't had any trouble being useful in combat or having a heck of a lot of fun RPing.
I'm glad you have fun roleplaying, but I am talking about mechanical performance. If everyone uses low stats, and/or if the DM softballs, then you probably won't notice a difference. However, if you play with someone who rolled 18, 17, 17, 16, 15, 14, you'll probably notice a difference in contributions; likewise, if the DM doesn't decide to go easy on you, you're likely going to take a dirt nap real quick as rocket tag tends to be unforgiving of people with low saves and special defenses.
I don't know if you can roleplay your way out of avoiding six bites to the face from a hydra due to the fact that you were not able to kill it in time, but if you can then I guess that makes my complaint less valid.
I realize that a lot of people do think a character with 15, 14, 14, 10, 9, 8 for stats would be unplayable, however. I won't be so patronizing as to say that I feel sorry for those people, but my experience has definitely been quite different.
It's not unplayable (in that, even if your character sucks, you can still play him), but it favors some classes (casters, say, a Drud) far over others (melee, say a Monk).
If you want, you can build a level 2 fighter with the stats 15, 14, 14, 10, 9, 8 and we can run some numbers. How would you say we determine if something sucks or not? I'm thinking we put it in a party and run it against some CR appropriate monsters. Or we could come up with some things a level 2 fighter should be able to take on his own (two CR 1/2 orcs, for example) and have a few mock battles.
