From URD 4.2, credited to the CRF:
When exactly is a site considered a Wizardhaven. For a DIY Wizardhaven with Hidden Haven I would assume only while that card is on the table. But for Isengard, The White Towers and Rhosgobel:Only Elven agents can move to a site that is a Wizardhaven
Are they always Wizardhavens?
Are they only considered Wizardhavens if your opponent is declared as a Fallen-Wizard?
What about if you are declared a a Fallen-Wizard but your opponent is not?
Or the most liberal interpretation, are they only considered Wizardhavens as long as a Wizardhaven version of the site card is a company's current/new site card?
And then an open-ended Agent question, that may lead to some opinions and house rules:
From the section on cards without effect on minion players -
This seems to make playing an Agent focused strategy against a minion player fairly untenable, especially if it's an influencing rather than combat focused agent strategy. Any thoughts on why they made this limitation? Obviously it's pretty tenuous thematically, but I could make the leap in logic that against a minion player the hazards represent threats by the forces of good and that your agents are there to influence elements to the side of the free peoples rather than Sauron.All Events that require an agent
So the rule is pretty clear, but I was looking for some advice for what to be aware of if I wanted to house rule ignore that and play agents without restrictions against minion players. In the Lidless Eye rulebook, the restriction on agent cards falls under the section for "overly powerful or mechanically doesn't work" rather than the optional list of "thematically doesn't make sense" so I didn't know if there was an abuse there against a minion player that I have yet to discover.
