So we're back to the dragon having to specifically fight in a suboptimal (or downright stupid) manner so that the party has a chance?
The dragon is stupid for the players deciding to do something to counter death from above?
Isn't that like saying your banker is stupid because you didn't drink expired milk and ran out of money?
I mean, I hope no adventure ever has a blue dragon in a desert. One of their preferred habitats.
A dragon is -mighty- in their element. Not all adventures automaticly put -every- monster in their element. And you can have a desert without having it be the sahara. Like, every desert in North America, for example. Desert != a featureless sea of sand.
The parties indicated, two fair examples of parties, have nothing they can do about the blue dragon. In previous editions they'd possibly have access to some more flight mechanisms, a method of teleport, etc. And the party's ranged spells and weapons were almost always more than the dragon's breath weapon or spell options, whether bows or magic missiles.
And you as a DM know this, so you either choose to set up an encounter that allows the players to use their ingenuity to 'solve' the dragon, or you choose to toss them to the wolves to sink or swim.
And whatever happens, it is your choice. You put the dragon there. No one else did.
So it's still not the DM trying to kill the party. It's a core game concept that is not jiving well.
Bull. No where in the books does it say or even pretend to claim that all monsters are appropriate for all games and all parties. The books actually tell you the exact opposite, that you are responsible for what goes inside, and that -appropriate- encounters are far healthier for games than random ones.
I don't know what DMG you've been pulling that 'core game concept' out of. But it ain't the 4th edition one.
You're not always within a minute of total cover. In fact, I'd imagine you're very, very often not within a minute of total cover. And the dragon only needs a minute to kill someone.
Yeah. And you know this as a DM. So be responsible. Don't blame Wizards because you don't understand how -your- choices of which monsters to use when leads to party trouble. The blue dragon is a -good- monster, but like -all- dragons it's not appropriate to -every- party -all the time-.
Absolutely - but shouldn't it work a little better out of the box, too?
It works great out of the box. The box even tells you how to use it, when, and why, and tells you to use it creatively and appropriately. Failure to follow the instructions on the box is not the fault of the manufacturers of the box. If you destroy your house because you used a chainsaw as a wirecutter, no amount of 'It should work better' will mitigate your own personal lack of responsibility.
Mind you, I think my problem would be solved by the harpy not having its aura (which is retarded, anyways) and the dragon's range being 10 instead of 20. So maybe those are just simple mistakes, hopefully not repeated often at higher levels or in later MMs.
Or maybe flight is just a lot more powerful than it used to be and hover is given out just a bit too much. Or maybe the loophole of Grasping Javelins should be championed as a solution rather than the clear loophole that it is. Dunno.
Grasping throwing spears isn't a loophole, it's an intentional feature on a weapon. Take number of spears that aren't polearms. Notice how many are thrown; all of them. The 'spear' entry informs you that they knew full well what they were doing.
But it -is- a solution, and a useful tool. I mean, hello! Encounter power that is tactically powerful on an item? That should recommend it right there.
Regardless, 'open featureless terrain' is frowned upon in 4e on every single level of the game. Flying enemies aside, cover and other such terrain is not 'optional' but is a given assumption of encounter design according to the DMG.
If a monster breaks because you ignore the DMG design advice, that's not the -monster- that is doin' it wrong, is it?
