Like it's already been said it's part of the gameplay to make user decisions and the adventures are balanced around that. If you pick snow shoes you must leave one of the others away as you gain speed advantage that allows you to block far more camps. If you don't pick snow shoes but take the other buffs you will have other advantages.
I think I already saw guides with snow shoes and it allowed several camps to be blocked with 1r attacks leading in to less losses than with the other 3 debuffs removed. The adventures are already pretty easy with 3 debuffs removed when compared to the levels and difficulty. This is why they probably added the bonus loot perk for people who do it with 2 debuffs on.
In the cold light of day your replies and thanks for them make a certain sense. Made me look at it in a different light good effort guys thanx. PS didn't mean to post twice
