[Lag increased from tuesday 1 Nov (Eu)]

Lag spikes are making the game unplayable for me.  I've found the game to be very unstable since day 1 of the patch,  and yes, it's been worse than ever this past week.  

Lately all I can do is craft,  and if it continues I won't be renewing my sub.

[Siege quests for Sapphire medals not updating properly.]

Absolutely this.  Thank you for bringing up this important topic.  Sieges have become a real disappointment for me as a support healer.   I never get mail from sieges anymore, and when my legion took Vorgaltem fort at the first Gelk siege, my quest didn't update.    Many others are experiencing this problem.   While  helping the faction is a good reason to attend sieges,  I also expect to get rewarded for my efforts , and that hasn't been happening at all lately.
