His overall report is in Darkfall's favor, commenting on how well the game seems to be holding up when there are huge amounts of players fighting in the same area. Certainly there are still client crashes and disconnects, but the performance is overall very stable for mass combat.
The only downfall to the whole system lies in the rules of the siege challenge. One of the rules states that if the attacking guild's leader drops offline at any time during the battle, the challenge is immediately lost. During Paragus's siege, the guild leader suffered a timeout, and the guild found themselves losing the challenge all due to connection problems.
While Aventurine patches up all of the problems, the overall report of sieges is good, in Paragus's opinion. For the full details, head on over and check out his writeup of the event.
