Take the example of a Ranger power that does Dex on a Miss. That power really reads "You do Dex on a Miss, unless your opponent is a Minion, in which case you do no damage." You need a special case exception to every rule in D&D that involves HP (which, in D&D, is a whole lot of rules). This probably increase the number of rules you have to know by 30% or more - just to cover the special case of "unless the target is a Minion."
I think Minions are a great addition, but here's the thing... if you are a DM, you decide what the encounters are. If you want no Minions, then don't use Minions. Easy.
However, I don't understand the above statement. That's not a bunch of special cases added, it's "misses don't cause damage to minions". The Player doesn't even need to know the rule. He looks at *his* character sheet, rolls, and says, "I miss, but I still do X damage". The DM knows it's a minion (or sees on the character sheet), ah, Minions don't take damage from misses," at which time the DM either can tell him it's a Minion and doesn't take damage, or he can even choose to describe the blow as striking but ineffectual.
Now the spellcaster comes along, casts an AOE spell that does half damage on a miss, tells the GM they missed but dealt Y damage, and the DM again sees it's a minion and realizes it does no damage, because misses don't deal it damage. Still, 1 rule that applies.
It's pretty simple, in my opinion. As a DM, you don't even have to bog the players down with the mechanics or even let them know it's a minion. Pretend to make a tally of the damage, and describe it as a minor wound and move on.
In reality, it's just one tool in the toolbox that 4E gives you, and if you don't like the tool, leave it in the toolbox. It's definitely not required to use it if you create your own encounters. Personally I plan to use the whole range from Minion to Elite. I love the system. It makes it more flexible, and can make combat more vibrant and exciting.
