Guys, I get it, and I agree, but I'm thinking that engaging in this back and forth with what can only be described as bullies is hurting the Dark Knight criticism and balance efforts. Some are more amenable to discussion, which is fine, but many are simply egging Dark Knights on (notice how very valid points are ignored each time, like Dark Knight's low usage rate?) for the sake of what seems like entertainment and fuel to discredit Dark Knights as being "too whiny" later on down the road, citing skirmishes they continue sparking.
Keep up the constructive suggestions, keep up the reports on how you experience playing Dark Knight and why you feel it should be different. The facts and data like the usage rates and general total damage taken are stronger if they are used on their own instead of in response to people who don't care about Dark Knight as a class or playing it long term. Let's debate and accept compromise when necessary, but develop a Dark Mind for ignoring sidetracking attempts at bullying, this person in particular.
