I had the same question. Why the alternative was not to just add skills only revolving around CC and being less "frequent", like one per class, with a high cooldown enough so that it would be situational instead of being the bread and butter of combat.
This is what scares me with the release on September though, the present batch will not have been tested by players, so if it's flawed, it will be flawed for release, that's a shame...
