It might be a step in the right direction but only a small step - e.g. you'll still have to rely on the AI targeting sensibly with single hit characters, and there are so many varied teams an attacker can bring, that for it to be useful you would need some very in-depth scripting. I would bet only a handful of committed players would have the time and inclination to use it if it's as complex as it would need to be, therefore it's likely to be massive time sink for little benefit. The majority of us probably want time spent on tidying bugs and finishing the PvE content first.
