Explain how there is "a lot more to this problem" then. You didn't give a reason, or present a solution either. It's all just ranting, whining, baseless opinions, and meaningless anecdotes.
An iintuitive solution would be switching the brackets to 10-39 and 40-59. But then you will get the same ppl crying about the 10-39 brackets, stating that they're getting wrecked. Creating a problem which does not exist, and asking for a solution to the problem.
Only issue is the expertise difference. Everything else, such as ability differences (no shoulder cannon on some, shoulder cannon on others) has been a factor since release, and will remain a factor as long as MMOs have levels.
In short, hurr durr cry more, none of you will ever be happy.
