Like Weeps said, to be effective, you need to get ccb and rigour, which is 340k tokens, which is around 85 dg or so. But, I suggest you try 70 def, and 90+ ranged, and try pking with that. Once you get sick of 70 def, go for 90+ def, and tank it up. I used to have a maxed tank, and it was quite fun, especially hybriding.
