Time for new mainguild Guild Halls?, Current update=gank heaven

The most recent update to the game included the following changes:
Archers guarding the Guild Lord area have been replaced by (pullable) knights.
Only one bodyguard guards the GL.
NPC spacing in the GL area is now slightly more spread out.
VoD occurs at 20 minutes
These changes will make ganking much, much easier.

Which guild halls are now weaker? And should we change the current guild halls?
