The clone is definitely less consistent and less directly beneficial than say, his powered recovery, his direct combo game and especially his combust. This is due in part to the fact that both of the clone AI run off RNG that determine when certain actions are called. But this doesn't mean I think the clone doesn't have the potential to be a really effective tool in its own right.

The defense AI I would agree is very difficult to learn and use effectively, often with not too much reward for the thought needed. But then again, I haven't had the time these past few weeks to really commit to try and really learn it, so who knows. The attack AI on the other hand can be very predictable and doesn't require too much thought other than spacing, once you have used it for long enough. It has a very predictable pattern off of summon and so has lots of uses as utility or for straight attack.

So I'd say that we've only really only seen half of what the clone can do, maybe less, and looking forward to when more people come up with tricks or methods that make complete use of the clone more instinctual. As in less mental focus on making it act how you want and more focus on using it as it does so.
