Without reward, what purpose does higher risk and complexity serve? If I can achieve far superior results on Paladin without half the effort, why am I going to bother with Dark Knight? There has to be some incentive otherwise its complexity for complexity's sake. Like Syzzle, I'm not looking for Dark Knight to be OP, but competitive. Right now, it's objectively inferior to both its counterparts in every way.
I get your point but turn it sideways :

"Why would I stick with a job that cannot compete with others, because it's easy to learn in design?"


I'm not saying that's the right choice of design, but there are flaw in both choices, either complexity = payoff, or complexity =/= performances.
