We do raid on Monday, Wednesday and Thursday from 20:30 to 22:30 and we also run a lot of m+ on daily basis from 15s to 19s.
We are currently looking for positive-minded people to add to our Raid Roster which is currently 8/8Normal - 6/8HC and we will be starting Mythic soon.
At the moment we are looking for DPS Ranged as priority but still considering melee DPS (1 DK DPS and 1 Shaman Enhancement ).
Our goal will be in Vault to push Mythic while making an optimal roster to achieve CE on the next raid releases.
If you are looking for a guild to play with, do content with and have fun with inside and outside raiding with also a lot of m+ then we are the right choice for you.
For more info just add me on Battlenet directly: OTPLoreTTV#2871
Its hard to tell you the exact number but between 10 to 18-19 players daily active at the same time. About the keys depends what level are you running, many are running already 20s.
