I usually don't have a problem with a bunker on the inside of a dogleg. I see it as risk-reward...if I choose that line, I better carry it far enough. If I don't, then I know a punishment awaits. Jim suggested "something a little more interesting" could go there instead...other than mounding, or a tree, or rough, I'm not sure what else an architect could do. A pond? I don't care for a tree there (punishes a short hitter who may be in the fairway, but blocked to the green), a pond is very harsh, and usually rough is bland and too playable for what was an errant shot.
Now, I agree with Powell...if I am going to carry the bunker, give me a reward...don't give me a shot from rough.
