Hi Devai
We might be just the guild you are looking for! We have several teams that raid only two days a week.
Zeroes to Heroes an Alliance guild on US-Stormrage is a community based guild that also raids. We support seven different raiding teams spanning all difficulties every day of the week. We also have a Sunday run that is specifically designed to give those without a raid team or looking to get into raiding a place to experience EP in a teaching environment with two normal/heroic teams for a more casual raiding experience. We now have a growing classic community, that is starting their first raids this month!
