New MA Parameters: New Dawn & Moneygrubber
Your suggestion ties RP/plot elements to game reward mechanics. I think it would be better to separate them.
BTW, you can nearly recreate the second scenario using a regular MA mission that the character exemplars down into.
And for a while things were cold,
They were scared down in their holes
The forest that once was green
Was colored black by those killing machines
Actually, it's the reverse, to better relate a reward to story. The points is to have heroic missions that specifically rewards teamwork within supergroups, and villainous missions that reward selfishness and might-makes-right.
In fact, it would be work better if the larger share of the reward was in clickies, so that villains were specifically tempted to take from each other.
But since the end result is the same, it's probably not a workable idea. Rewards and game can be tricky, and as much as I'd like to see this kind of thing in game, the redside concept would probably bring out some bad elements in players. Thought I'd throw it out there, so now I'll reel it back in!
Here's an idea for two new Mission Parameters: The New Dawn (blueside only) and Moneygrubber (redside only).
The New Dawn is a long Defeat All mission, that limits map selection to one of several Rogue Isles city maps. The Hero invades the Rogue Isles just to rescue mugging or extortion victims. The victims are incredibly grateful and actually stop to thank the heroes for the pains they go to save them, specifically thanking the player's SG (if they are in SG mode). This mission offers no XP, Debt repayment, or Influence, but instead offers aslight increase in the earn rate of Prestige.
Moneygrubber is a high-risk bank mission to rob the Paragon City Treasury. Longbow and the PPD are heavy, and instead of experience, Prestige, or debt repayment, Infamy is the lone reward. It uses a special map series that takes the player deep into a Longbow base, to potentially fight off a Vindicator (or seven).
