How can we get more in depth character customization?

Not sure what you mean by DoT's cause I still see them around.

I think they mean the whole gauge design thing or whatever it's called.

When they were revealing info about 4.0 in that live stream on twitch it was mentioned that they went that route due to players complaining about not being able to manage their dots.

Also there's mmos with actual choice and while some situations/dungeons say certain classes are better for certain things. It's not really forced there however a lot of those mmos are sandboxes and the communities there seem to be able to handle it.
