I suppose the real problem is that Bodybuilding/Willpower are direct counters to 'messiness', 9 times out of 10. Once you realize that and start pumping them up, the game tends to become less challenging. If you don't pump them up, though, the game is simply frustrating.

Even if an enemy teleports one of my characters, I usually don't care. It's a fair chunk of damage, but it's not like I can't feather fall them right back with either of my 2 mages. Or turn invisible, or cast Become Air, or put an elemental shield on them.

The only thing that really screws with me is when the entire battlefield is covered in smoke - and that's more of a frustration than an actual danger.
