Can you imagine the feeling?
I gather from context this is pretty cool. Mind explaining that to a non-WOWer?
Sure. The entire population of the game (several million players) is divided into separate servers, or "Realms" to handle the load. Guilds and players are tied to one specific realm, which generally has tens or hundreds of thousands of players.
Guilds on various realms compete with each other to defeat the top-tier endgame content (raids). This particular current raid (called Blackrock Foundry) has a final end boss named Warlord Blackhand. There are several difficulty levels you can attempt, with Mythic being the most difficult.
Mythic requires near perfection; an absolute top-notch team, the best gear in the game, and lots and lots of practice and minmaxing.
The first guild to complete this challenge gets a very special achievement, called "Realm First". This tier of content has been out for a month now and it has taken this long for a guild to complete it, but it happened while I was logged in. When a guild downs a boss for the first time ever on a realm, it is announced to every player on that realm at the time.
So, this guild (Royal Militia) was the first guild on Kel'Thuzad (our realm), to defeat Blackhand on Mythic difficulty. A one-of-a-kind achievement that nobody can ever get again
I came so close to getting realm first Paladin in Wrath. Missed it by 6 minutes.
It's super funny too because like Royal Militia was super behind Divinity. Divinity broke up last week.
The hardest thing about mythic raiding is mythic drama.
I love me some wow drama.
