What level offense (and defense) is needed to stay safe at different sizes at OOP? At 415 and 540 I assume you only really need 5k of each or so, since there are so many targets. But I'm seeing people quoting 30-35k MO for killers coming oop - wouldn't 15k MO be enough deterrent for them to skip a 1k acre prov and go looking for a "free acre" hit?
And does anyone actually have a plan drawn up for hitting 30k+ ? I'm planning a fairly tightly run sequence, and am only hitting around 15k/15k Off/Def at best... how much more can you really get? Especially since I'm ToGing hard to get everything trained, and most don't have that option.
Yes, I could go pure defense, but since I'm an attacker (ignore the faery part, just think generic attacker) I'd much rather use my offense as a deterrent instead of defense. Then I'm ready for war and can get a plunder or two as I find targets.
So, again, what is a safe OPA or Offense to OOP at? For 1,000 acre, for 900 acre? Do I really have to throttle back?
