Wunshi's Focussing sorta makes Fo7 obsolete anyhow. Once you have it, no one you group with will want the lower buff ever again. With how much easier 66-68 spells are to get than 65s, I don't think stopping at 65 is really the thing to do. Then, of course, if one is 68, stopping there looks bad cause you can't zone into RSS, which is huge as a source of runes, gear, augments, and mad exp. And then you're 69, and looking at 70, where you can get Call of the Wild and "that other AA"
Advancement is so steady from the mid-60s, with power gains really attractive (as opposed to just
good like they always were) at each ding. 62 is the right spot for Cannibalization, in my opinion, since there isn't an attractive place to sit without levelling after that.
The sky is the limit once 70
