PremadeIQ flags pre-arranged groups (premades) in Epic Battlegrounds — and it is built to do that fairly. Here is exactly how it works, and why an ordinary player will not get mislabeled.
The addon quietly records each Epic BG scoreboard — who played, which side, damage and healing, and whether they entered as a mercenary. The Uploader sends it to the server. Over time this builds a history of who keeps showing up together.
Who is whose alt. Characters on the same Battle.net account share account-wide achievements earned at the very same moment. We use that match to fold a player's alts into one person — so a leader and all of their alt characters count as one.
Who is a mercenary. A player fighting for the faction opposite their home faction opted into mercenary mode — a deliberate choice they make at an NPC, never something the game does automatically. This matters: premades often opt in together to slip onto the enemy side and stack it.
A known premade leader is marked manually — just one character. From there the system automatically follows every alt on that account.
From certain to likely:
A marked premade leader, or any of their alts.
A player confirmed to be in the leader's premade, in either of two ways. By history — they keep landing on the leader's team, measured by share of their own games (not raw count, so a regular who just plays a lot stays clear). Or by mercing in with the leader — they entered as a mercenary alongside the leader this match (a deliberate, coordinated act; more on that below).
When mercenaries pile onto one side well past the usual one or two but none of them is a leader we already track, the stack is flagged as a likely premade — clearly coordinated, just not yet tied to a known leader.
Mercenary mode is switched on by hand at an NPC — a deliberate choice, never something the game does to you. So when a known premade leader takes mercenary, and others take mercenary onto the same side in the same match, that is direct, joint coordination, not coincidence.
We weight this signal above any amount of co-play history — and it is hard to argue with: you chose to queue in with them.
This is the part that matters most.
The addon also checks the enemy roster against the known-premade list as a battleground starts, and warns you — by sound and in chat — before the fight begins.
PremadeIQ runs on shared data: the premade history is only as good as the matches the community feeds in. So access is reciprocal — you contribute your own battlegrounds, and in return you get everyone else's.
No subscriptions and no paywall for the core: share what you see, and you see what everyone shares.
In short: we remember every match, work out who is an alt and who is a mercenary, mark the leaders, and then — in descending order of confidence — light up their accounts, their regular teammates, and their mercenary stacks. But only where the evidence actually holds up.
