Hi Stere,
Unsure if the high pop server is adeal breaker or not for you as ours is not, also not sure what difficulty you looking for but look at our info below.
Retaliation is a heroic progression guild that has been raiding and PvPing in various games for over 10 years. We enjoy giving each other a hard time while still being successful.
Retaliation raids on Tuesday and Wednesday nights 8 PM to 10 PM ET. We use Discord for voice communication and go with a work hard play hard mentality. We also require a mythic+ to be completed each week to assist with progression.
