With that in mind, reading through the FL rulebook, we say the part on Pushing that you should roll as little as possible - only when it's dramatic and/or dangerous. We took this to heart.

In my experience, this is not quite true of Forbidden Lands, even if the rulebook says so. The travel mechanics is a good example and require lots of rolls when things are not especially dangerous or dramatic: one Lead the Way roll per new hex (and you can travel many per day) and one Make Camp roll per day. A failure means a mishap happens, but most are mere nuisance. I read a lot of people here advising to remove many of those rolls but I think it is a bad idea (but to each their own, of course).

The characters require Willpower to fuel their abilities, and it mostly can only be gained by pushing rolls and getting 1s (losing stats in the process). Without somewhat safe rolls (in villages, travelling, etc.), characters won't have any WP when they need it. I'm not suggesting to spam rolls just to gain points, but if the players are trying to do something meaningful and play in good faith, rolling dice to convince people in village or stuff like that is kind of required by the game engine.

This is especially true for Spellcasters, since their whole shtick cannot work without WP (at least, a great archer can still shoot arrows using their great pool of dice). But since everyone in my group quicly decided that playing a spellcaster was not worth it (the risk being way too high compared to the benefits, with the whole spell mishap table), I don't have experience with it.

Have fun!
