Hi Alcyone
Welcome back to the World of Warcraft! I think we would be a good fit. Our guild “Excuses” is on EU Silvermoon. But with cross server guilds you should be able to jump in with any guild.
We are a HC raiding guild. Our focus getting at least “Ahead of the Curve” each tier. We also run mythic + keys as a team looking to get keystone master/hero if that also interests you.
We have a Discord server and raids are a fairly chilled event. We are looking for DPS still for The War Within. We do have some healing spots but can be very competitive as we normally have a few healers.
No role playing needed 
We raid 2 days a week, Wednesday and Thursday evenings.
Feel free to get in contact Battle.net: Norvo#2341 or Discord norvo.
