Ironically, I keep getting messages that say things like:
"Placing this enemy will limit your map to players of level 43 or higher"
Usually I see this when I place an 8472 or a Borg.
And I realized Cryptic must have this level of control somewhere.
I remember the Hirogen Bridge crew in Trapped.
There's a Tactical, an Engineer, a Navigator and a couple of others.
They're always in the same places each time, so strict defining must be possible.
And regarding enemy mobs:
1. You can create easy kill mobs by just saying all ensigns.
Class is irrevalent.
2. What if you wanted to give the boss (captain or most deadly npc) a unique skin, to make him stand out?
Then it shifts which npc he is, meaning some lowbie is now wearing the skin the boss was intended to.
