I've now played at least a couple hundred games with Adventures. I like the page line. I've yet to witness a game where "the Warrior Strategy" dominated, but I've seen several games with strong, chainable attacks (Torturer, Rabble, Witch, Giant, even Saboteur), where the game was a race to get a Champion in play and wreck havoc for as long as possible before the opponent managed to play their own Champion, or resigned. All in all, I feel Champion becomes way too good with that kind of Attacks, and it comes with a weaker version of them built-in (but I feel it's Champion's fault, not Warrior's).
It's probably important for the Page line to provide some form of defence from attacks, given the potential pains caused by Champion and Torturer together.
Here's an idea for a different, probably somewhat more balanced, Champion:
+1 Action
For the rest of the game, when you play an Attack, it doesn't affect the other players, and when you play an Action, +1 Action.
(This stays in play. This is not in the Supply.)
What do you think? Are there any changes
you would make to the Page line? (I suspect a favorite is to have Warrior leave Travellers alone).
I don't own Adventures IRL, so I don't think I'll test this any time soon, I just wanted to hear what you thought.
