Voss said:Or, the other situation that comes to mind, because of the dragon fight, which dragged out beyond the point of ridiculous, is that if the characters are 4th level, with 10-20 more hit points each, +2 to hit, bonuses from magical weapons, more powers and so on, will change from a grind, to almost easy. The dragon had a hard time dropping the PCs at first level. With 3 more levels worth of resources, I'm not convinced that it really can, and that thought also makes me sad.
I don't think it's actually supposed to win though.
It's like the CR system in 4E. A CR 20 monster is NOT a threat to a 4 person Level 20 party. It's only supposed to consume 20% of said resources and thus, the party is actually expected to win.
I think the same thing applies to monsters/encounters in 4E. If the XP budget at 1st level is 600xp, the PCs are expected to win as long as the XP total of the creatures doesn't exceed that amount by too much.
To actually have a "oh crap, the PCs will definitely be facing an uphill battle", you probably have to exceed the xp budget by at least one PC's worth of XP if not two (if a 1st level PC contributes 100 xp to the budget, to seriously challenge a 6 person party, you need to budget at least 700-800 xp worth of creatures).
Doubling up would probably result in a TPK situation as basically, you have each party member fighting an elite.
