For all the good that World of Warcraft‘s level scaling has brought to the game, it has made farming for old appearances slightly more difficult. Now that the game’s dungeons are all synced to drop personal loot, it can be hard to farm things that you can unlock but wouldn’t drop under the game’s personal loot restrictions. Good news, then; when Battle for Azeroth rolls around, a new style of loot will be put into place for legacy loot in content that you outlevel by a significant margin.
Any dungeons or raids that you enter while at least 10 levels above the “designed” levels will activate Legacy loot; every boss will drop as many items as possible, and all loot can be freely traded between party members when things drop. Loot is split between players, however, so if a boss drops four things for a two-person party, both players will get two items. It should make for an easier time getting cosmetics and farming for them, so that’ll be a welcome change – especially with a whole new expansion’s worth of stuff to farm for transmog purposes.
