Ok, this was more heated than I expected.
For those who don't understand the issue here's an analogy:
Imagine you was walking along and suddenly realize that you are wearing a green shirt when you know that you don't like wearing green. And for a moment you don't remember choosing a green shirt and thought you were wearing blue this entire time.
The analogy isn't perfect, but that's kind of what it feels like.
Regarding keyboard use, I find that moving the camera with a mouse pales in complexity to using skills, moving, dodging, switching targets, and using toolbelt skills all roughly at the same time. The coordination and dexterity required for the keyboard seems higher than the mouse to me. Then again, being left-handed, I probably off-load more tasks to the keyboard than most people.
Finally, about this being a real "issue" or not, who are you to say whether it's an issue for me? I don't deny that the Wintersday JP has an issue with large characters because it doesn't detract from my experience. Please respect that I have a different gaming experience than you.
