There are a lot of Week events:
-SC event
-RVR Event
-PVE event
-Ranked event
Why not add an City siege event too?
Rewards similar to RVR event:
-Basic: Potion of acclaim; 10 gold or 25 Warcrest
-Advanced: 50 Warcrest; Event item
-Elite: Stalwart soulstone; 50 gold; 75 Warcrest; or


Goals:
-Participate on 2 citys
-Win 1 city
-Kill 100 players on city siege.
This will motivate to people to play city. Only playing a full city can obtain the first reward, and winning 1 city per week.
I think can be a good idea. What do you think?
