'supposed' to? No, not especially, but remember the XP value of 4e monsters doesn't factor in powers. You CAN add an encounter power to a monster, it won't change the numbers, though it may in practice make the fight harder. There's always some slack in any point system.ah - so, you were also supposed to add dailies to the bad guys after level 5?
The point Krusty makes is that difficulty increase isn't linearly incremental. It is more like a ratio. If you add a level to a level 1 monster you increase its toughness by something like 25%. If you add a level to a level 25 monster you increased its toughness by maybe 5% (probably less). This is just an inevitable consequence of linearly incrementing numbers starting at a baseline non-zero. In fact the XP values of monsters DO linearize things per point of XP (level 1 goes from 100 XP to 125 XP at level 2, but level 25 is about a 5% bump). Up to a certain point then the level +1 to level +5 scale works, but it delivers less and less challenge increase. This is why Krusty said to add 1 level per 5 levels, that means a level 25 party faces a level 30 encounter as a standard encounter, and a level 35 encounter as a true struggle. In reality making this work correctly would require making hit points, defenses, and attack bonuses slightly non-linear, but it is probably just not worth the added complexity. It is worth noting that things like the expertise feats actually do move things slightly in that direction.
