No, Sylvanas Windrunner being called a “split leader” in the mobile battler Warcraft Rumble isn’t a reference to the fact that her story appears to have been written by two different people; it’s a rewards mechanic that’s specific to the mini’s arrival in the Season 10 update this week since she’s a leader of both the Horde and Undead.
This new mini essentially lets PvE players earn split sigil progress, family crests, and tome progress for both of the Horde and Undead families she’s part of; can be selected for the dungeon week of either family as an alternate means to coins and rewards; and will see specific dungeon effects apply to either one or both of her families. The character doesn’t see any changes to PvP rewards beyond 200 honor and 100 crests for both families.
If all of that sounds interesting to you (and not utterly confounding), then there’s an event going on that will offer players different challenges to complete that award tickets, which can then be spent to unlock upgrades for Sylvanas. The Season 10 update post also outlines the character’s moves and reminds fans of its upcoming December beta test for PC.
