From Mystickittie (Sunday Funday Coordinator):

The Sunday Funday event this Sunday, Oct 22nd, will be open world pvp event. With warmode on, as a group, we will do the spark quests for anybody that needs them, the available pvp quests, etc. If we have enough for a raid group we will work on the Dragonfight Club achievement, kill rares in war mode, and overall be a group of terror against the alliance. This will be a horde only character event due to not wanting to kill our own guild members for Sunday Funday!

We will start grouping in discord voice at 4:45pm EST this upcoming Sunday! The event will run until 7pm EST.
