This was what PvP is all about for me.
Dawnbreaker EU.
DC holds the map and EP is trying to start their breakout.
Epic numbers attack from the front, DC answer with engines & skirmishers, gat goes down and the zerg comes in, engines greet them, they make it in anyway, groups fight, individuals fight, eventually they are driven back and walls get repaired.
But they are not done... they sends troops to one side to knock down the wall, but while DC defends EP team 2 is knocking down the opposite side, the enter, more fights on many levels.
This goes back and forth for nearly two hours before they finally take the fort and we defeated remnants fall back ready to defend the next threatened castle.
The player numbers must have been in the hundreds, the fights were from 1vs1 to many vs many, the result was in doubt until the end...
This is why, as a new MMO player, I love Cyrodiil.
Don't change it.
