Hey Urukaij,
I am the GM of a casual guild on Stormreaver [EU] (8/8 N, 8/8 HC, 1/8M), we are a quickly growing guild with new members joining every day. During the week there is always active people running mythic+ and socializing. On the weekend (Friday - Sunday) we have raids in the evening 8-11 server time. Friday is out heroic clear night, Saturday is a normal run to gear people and alts. Sunday is our mythic night for people who want to come for something with a bit more difficulty.
We are a very relaxed guild and there is no commitment to anything you do. We provide the opportunities such as guild raids and we only ask that you have a positive mindset and are sociable with other members.
Please add me at BigFatSalami#2332 if you would like to have a chat and ask some questions 
I will leave a link to our post below:
