Well, as I mention in the guide.
I'm doing PURE DDI balance.
As I prefer more damage than submission moves.
However, I do believe sub balance is much versatile all-around in the higher levels providing you are able to build it.
So, if you think about making a sub finisher, go ahead, it works really well with your versa too.
Kiean, my tag/trade/federation partner is doing the same build as you, you can ask him if you want.
