I'd like to like this card, but I'm hard-pressed to find good use for him. A cost of 2 for 2 is usually a good deal, but only if it's going to stick around more than a turn or two. I swear, Brandybucks can be more unreliable than those damn fool Tooks.
You can only put him out for free after exploring the previous active location (unless there wasn't one), so chances are your overall Willpower isn't hurting. So then you travel to a new location and play this card for free. That's an extra 2 for questing NEXT turn, which might allow some other character to fight instead of questing. But if you use that extra Willpower to explore the active location next turn, you'll also lose your extra Willpower to the bottom of your deck. If you're planning to stay at a given location for a while, this may be helpful, but that's usually not a good idea unless you have some form of location control up your sleeve or you're taking advantage of Path of Need.
Conceivably, you could use him to get extra threat reduction from Elevenses, pulling just enough Hobbits from questing to avoid exploring the active location, but again, this assumes staking out a location for multiple turns.
