Agreed.
However, regardless of how the game is played, earlier versions had definitive statements that the players could not just say "I target the leader with Hold Person". The player had to say which NPC he wanted to target.
In 4E, there appears to be this hand waving of "Oh, go ahead, tell the player which NPC is the leader so that he can cast Hold Person on him". It gets back to the player entitlement issue that some people dislike.
Some people consider it cinematic license. Others consider it metagaming.
Others consider it simple observation.
Player: "Ok, I target the guy with the armoured guard each side of him. The guy shouting out all the orders."
DM: "What? How'd you figure out he was the leader?"
Player: "... You're joking, right?"
The PCs know there are minions because the encounter outnumbers the party.
The PCs can tell who the minions are because the minions are the first troops sent forwards, just like the expendable peasant infantry were the first ones sent forward in many medieval battles.
If you continue on the theme of minions as expendable troops, minions will most likely have standard-issue equipment, because that's how you equip expendable infantry. It's cheaper, and helps build a sense of esprit de corps. So there's real life precedent for minions to all look the same.
There's no metagaming.
Furthermore, making minions take more than one hit would mean you had to use less minions. Four minions dying in one hit each replace one standard monster who dies in four hits. If minions take two hits to kill, then two of them replace one standard monster. Three hits, and they might as well be a normal monster.
And the problem with requiring an odd or even roll to kill a minion is that 25% of the time minions will take three or more hits to kill, and it will not be uncommon for minions to require more than four hits, making them
tougher than a standard monster. That's terrible design, and a possible TPK.
