Evening.
I've got a weird, GM related problem, and I've no idea how to fix it.
In the most basic terms - as a GM I'm pissed. I'm really really pissed, because I kept telling my players they have it too easy and that the difficulty should be upped, but they insisted that everything is fine, and during the last session they basically killed a boss NPC with one hit. I've already asked how to increase difficulty on the fly (http://rpg.stackexchange.com/questions/51295/how-to-increase-difficulty-on-the-fly), but there's also the whole "I'm freakin' pissed off" thing.
