While we don't yet know very much about the story content coming in World of Warcraft: Battle for Azeroth's upcoming 8.2.5 patch (not for the Data Miners' lack of trying) we do know a little about some of the new features that the patch will bring us. Blizzard has released the their official patch notes and a hand ful of feature articles to clue us in on what is to come. Along with the return of a revamped Recruit-A-Friend system and the much needed model overhaul for the Goblin and Worgen races, they have announced a feature that has been in demand for as long as I can remember: Party Sync, their implementation of teammate-based level scaling.
For those of you unfamiliar with the concept of teammate-based level scaling, it is a system put in place to allow friends to play the game with each other no matter what the difference in their character level. While several other MMOs have implemented systems like this, the strongest example that comes to mind was the Side Kick system in the now defunct City of Heroes MMO.It allowed a low level character to scale their abilities up to the general power level of their more experienced friend or vice versa, depending on who was party leader. World of Warcraft's implementation appears to only scale downwards, and will assuredly have far fewer capes involved. Even so, it will certainly be useful in welcoming back my friends that are returning for WoW Classic or grouping with my wife's newly created Allied Race characters.
