Cute. But statistical modeling for monetization doesn't bother taking those people into account, because they really don't matter. (Either because there are too few or because they really do fit into a box somewhere else on the scale).
I'm not sure about that. Watching a lot of streams of gameplay for other unreleased MMOs (which I've been doing a fair amount of this week) has revealed a particular pattern: the PvP fans are a demanding lot, and they really want structured PvP. If ESO had some form of small group or solo PvP, whether in the form of Battlegrounds, Arenas, or whatever, I'd say it has a decent chance of attracting those players. But with just the massive AvA PvP? I have doubts.
