It does get a little comic when you have several characters of wildly differing sizes, but I'm not sure that's really a problem. As for adventure ideas, part of the interest in playing a drake for me is in dealing with and (hopefully) overcoming the "Ahh! Monster! Kill it!" reaction, so I'd find some amount of socializing desirable. Obviously there are some scenarios where that strains credibility; I'm not going to be invited nor welcome at a society ball no matter how profusely I insist that I'm just here to chat. I'm also ready to accept the realities that go along with being a large creature. For the most part, if medium creatures can walk comfortably through a space, then I'll be able to squeeze through. I may not be able to turn around, but that's probably fine. And while squeezing is a bad condition, it's no worse than most of the other bad conditions. As long as combats only infrequently take place in long narrow hallways, it shouldn't be a major problem.
