And why do you need a complex environment for a way above deadly demon encounter to be challenging even if it is only one encounter that day?
Basically, I'm being told that two or three time deadly encounters in a neutral environment against PCs using feats, magic items, and multiclassing where they can nova is just not enough to challenge them. I don't agree with that. Why can't monsters that add up to a two or three time deadly encounter in a neutral environment provide a challenge? If they can't, then why is WotC designing so many modules with these one or two encounter day scenarios with single powerful monsters? Why are the people that make the game not designing their modules more like Flamestrike or the others saying single x2 or x3 deadly encounters in neutral environments are not enough to challenge PCs with feats, multclassing, and magic items?
I'm going to challenge your statement regarding a neutral environment. From the scenario you explained, the environment was anything but neutral. Featureless, perhaps, but not neutral. It was HEAVILY biased towards the PCs.
I'm having trouble finding the post where you outlined the battle, but going from memory you gave the party a significant terrain advantage: they were able to make a full rounds worth of attacks in total safety before the enemies were able to move into a position to counterattack. The fact that terrain (yes, 120 feet of empty space is terrain) prevented one side from effectively acting for a whole round was a HUGE advantage to the party.
Consider how your party would do against a group of spell-sniper warlock/sorcerers using Distant Spell to Eldritch Blast them from 720 feet on a featureless plain. The party is only 120 feet from their effective range, but the time it takes to get there grants a clear advantage to the other side.
Consider how they would do if they were ambushed at night (because magic made their guard sleep) and required to spend their first round getting up before attacking.
Consider how they would do if they were magically incapacitated (no save) for a round while the enemies got a free round to attack them however they would like.
The latter two cases are mechanically identical (one round wasted before acting offensively), yet grant one side a clear advantage. Costing one side a round to cross empty terrain is no less biased.
If I had to guess, I would assume your stated aversion to creating complex terrain leads you to believe that empty terrain is inherently unbiased. This could not be further from the truth. Terrain is just one more factor of combat that must be considered. In your given situation you accidentally gave a massive terrain bonus to one side, and it made the fight incredibly one sided.
