No, you see, we need to stack Rage five times because...
Personally, I just don't want to have to deal with a power I'll probably forget to click half the time--and most of the other half of the time click it two seconds too early and be hit with a debuff because of it.
If I could throw it on auto and be done with it, that'd be awesome >_>
It's the casual vs hardcore argument, I suppose?
