Oh, definitely. I played a star pact warlock in my one long-running campaign, and I felt that pain. (Cross that with the damage-type/flavor issue I mentioned earlier and it's twice the pain!) It's a bit of a miracle I lasted to the end of the campaign, but the DM was an execellent role-player, and he had bound my warlock well into the story. When we finally got to the pivotal moment, and I realized a little "flavor" tweak he'd made to my character's initial build many years before was the key to the whole thing, it was quite a thrill. But every time we rolled initiative I winced, knowing a couple of hours of whiffed die rolls lay ahead. I won't bother going into more detail, anybody who place a V class more than likely knows.
