First off, _Castle_, let me say thank you for looking into these issues. I'm obviously not alone in the defender community when I say thank you for at least addressing some of our concerns.
That said, I do have one issue with your post. Throughout your post, you mention powers (with status effects primarily)that work as well if not better in a controller's secondary than in a defender's primary set as being working by design. While you do give the defense that the damage component of some of these powers is higher for the defender than it is for the controller, I think you're failing to realize the reason most people take the power in the first place. It's not for some minor damage component - it's for the status effect the power gives.
Now, admittedly, controllers should certainly have a vital role in subduing mobs and otherwise taking them out of combat. However, I urge you to note that those status effecting powers were given to defenders for a reason - they do mitigate incoming damage, which is crucial for the sets that are not so heal intensive.
My problem, I guess, is that the design team has been very careful to make sure that defenders don't step on a controller's toes, but I want to ask - who is making sure the reverse isn't happening? With so many defender primaries shared as controller secondaries, this problem has been resurfacing time and time again as this sharing has blurred our role in a group. Obviously, removing the shared primaries/secondaries is not an option - especially at this point in the game, but I'd like to ask you to take another look and see how powers and power sets can be differentiated between defenders and controllers so that each archtype (both defenders and controllers) can bring something useful, different, and easily distinguishable from the other archtypes.
As a final note, I want to go on record saying that I'm NOT calling for a nerf to controllers by any means. I would, however, like to see the effects of powers that, for example, a storm defender uses be appreciably different than the effects of powers a */storm controller uses.
For example, if the devs have decided that controllers should be better at any status effects of some powers (like, say, thunderclap) than defenders, that's all well and good, but maybe defenders should get some sort of buff or debuff to their version of the power to make up for the reduced status effect.
Just my thoughts. Thanks again for your time, _Castle_.
