So hear me out before anyone starts getting their knickers in a bunch.
The "Challenge Zones" are actually the current pvp zones minus the pvp. Before, I go further the regular pvp zones are still there but, get sort of the Echo treatment and can only be accessed through the arena. So they still exist just in a different way. (Gotta be fair to the pvp folks too, I used to be one on live!)
The Challenge zones would be set up to introduce max lvl challenges by whatever the zone lvls are. Imagine the new ASF/801 series but in a zone form. Because, face it the hardest zone right now is the new Dark Astoria and frankly most of my toons can easily defeat anything in there.
With IOs being available at any lvl the need for more challenging content across all lvls is needed. Lastly all zones are co-op except one.
So Sirens would still have the Arachnos vs Longbow function but spearheaded by max lvl AVs and different buffs/debuffs/badges when one side wins or the other.
The "Battle for Sirens Call" could still be a zone war but heroes and villains would have to target pve enemies and AVs to stop an all out war breaking out that would engulf the world.
The "Bounty" option could now be a special AV thats introduced at the conclusion of the Battle for SC.
Bloody Bay could be the same but with max lvl enemies and enemy AVs now guarding the meteors. With zone GM events dropping the defenses around the meteors for a period of time. Example, defeating Shivan Oblititerator to drop meteors enemies or just fighting the now buffed enemies around the meteors. Now that being said the reward has to get boosted because the challenge has increased, say 10 shivans now instead of 3 or a special buff (toxic/nrg def) or a special debuff (-def/-regen added attacks).
Same with Warburg but high lvl Arachnos/AVs guarding all the stuff to make it a better challenge. Obviously Marshall Blitz would have to the big bad AV, and have him as the final thing to defeat to unlock the nuke launch. As with an increase in challenges the reward would have to be increased.
Finally, Recluse Victory, obviously max lvl uber AVs. Since this possible future is in a constant of flux based on who wins, so is zone access.
One week it will only be unlocked for heroes and the next it will only unlock for villains. Just as the battle inside determines who wins the future outside it is also determined by who can access it. Sort of like the TF of the week but on a weekly rotation. Then obviously new buffs/badges would have to be introduced.
Zone bases would be turned into access points based on side. With Rogue/Vigilantes accessing either villain or hero. Obviously, if you're a hero you're not going to be able to access a villain base and vice versa.
This is just a basic shell of an idea, but, the start. Any ideas? Critique? Got to hell Warpact don't mess with my mostly empty pee-vee-pee zones!
