-PvP Arena

-Battlegrounds

-Dungeons

-Raids

You always go through a loading screen to get into a dungeon or into a arena or battlegrounds, you also have to queue up for it so im sure theres some way to figure it around that to recognize it on one of those.

arena is self explanatory, just record the match.

battlegrounds could record kills or captures or just full match

dungeons you could have it record just the boss fights same with raids
