There are so many different views on this but here is my advice to players who are just starting out and want to tackle this very difficult quest pack:
Zargon should go through and remove 1/3rd to 1/2 of all the monsters from each quest. Don't have to do anything more than this really, besides dealing with the Yeti Hugs (I recommend going with Avalon Hill's suggestion in the companion app that Yeti Hugs simply don't do anything when there's only one Hero on the board.. and in group quests you can roll a 5 or 6 on two red dice to break free immediately or try again at the start of each hero turn).
Another suggestion I would give is for the Solo Quests, just use a party of heroes. Perhaps 4 is too many, 2 at the very least. To compensate, the rewards should be multiplied by the number of heroes. So if you find a sword, then you should find a sword for each of the heroes, one healing potion becomes one for each, etc. Very easy to implement and remember.
Now this won't work with the Companion App but it sorta can still, because when you reveal a room and it has four monsters, you just point and click and kill two of them (or whatever). Then proceed as normal with your rolls and things. When it said a rewards, double, triple, quadruple it.
Now it won't always be perfect because the Wizard can't use all the same gear as everyone else. But you can give him a potion or something. If the reward is a weapon or armor, give him a staff or bracers. If it's an artifact, give him the Talisman of Lore or a spell scroll.
I would have similar advice for the Mage of the Mirror.
