So mythic has mad many changes to RvR since the release of WARHAMMER... one of their big changes was city sieges. See how some of your fellow WAR players feel about the current state of the city sieges.
Sneak Peak:
1. Rotating PQ's Lots of variety keeps things fresh (I want to see Battle for Praag tug of war in IC / Mass escorts where you need to kill the enemy hero before they kill yours).
2. The city siege is open for 24 hours (giving everyone a chance to do it) but the instance is locked out during the server offpeak hours or maybe the guards increase during the nightwatch to such a level as too make it near impossible.
3. Random Instance (currently going in)
4. One hour maybe its 6) need a safety net on this if you return with 15 minutes (post crash) it will let you resum in the instance you were in before. Also if you leave when there is less opposition then there should be no penalty (enabling those who want to defend all instances to still do it)
Do enjoy!
