Cyrodil needs a full reset when the score resets.
Keeps, scrolls, and even quest progress if possible! There are two reasons why this is needed.
1. The faction in the lead of one campaign is usually in the lead of the next campaign. This is usually because the lead faction will have the most scrolls, keeps, and players when the next campaign starts. This can be changed if a rival pvp guild comes in and tries to take as much of the map and scrolls as they can before the score resets but getting enough players together after being so discouraged by a loss can be difficult and pretty much impossible if your faction is last. A full reset of cyrodil when the score resets would fix this and give even the last place faction a chance.
2. Cheaters, boosters, and exploiters. Whatever you want to call them there's a bunch of players who use the score reset and boosting to get easy emps. I don't really care about getting emp myself but for some players its a big deal and I don't think "rainbows" should be able to cheat the system for something that should be properly earned. If cyrodil got a full reset when the score resets these people wouldn't be able to to stack massive keep defense ticks in one campaign so they can emp in the next.
Edit for the mods. "Rainbows" in this context is not a slur against gay people. It refers to pvp'ers who help the enemy factions. I know you guys love to go overboard censoring posts but your diligence is not needed this time.
Please reset cyrodil when the score resets. My pvp guild and faction wins almost every campaign because it doesn't and its unfair to the other factions.
