I feel like the point is being missed. It doesn't matter if there are warnings. There a million times in a game where players are warned against doing things- even staying alive (Fuck you, Nettie). There are multiple fights that are above the level and capability of players at there level with their current armor and weapons. It isn't fun. If you have to have the right party, be in the right place, and get the right rolls to survive the first round it's not a good fight. Also, it is in the game for us to encounter. Saying we should stay away from it seems like a silly things to say. Experience the game, but not that part!
Don't just assume everyone agrees with you. Because I for one - do not. I like challenging fights that force me to come up with different approaches.
