On to Maelstrom Weapon. This is actually something that was changed in the beta a while back, and the tooltip just took some time to get updated: Lava Burst is no longer affected by Maelstrom charges (this won’t affect us for now, since the first rank of Lava Burst is at level 75). So it looks like you’ll be limited to Lightning Bolt or Chain Lightning for your instant-cast damage spells, clearly a PvE nerf. Chase actually sees this as a buff for PvP, though - now you can Flame Shock, crit Lava Burst, and instant Lightning Bolt for some serious burst damage.

As far as Predatory Instincts goes, the patch notes say “The tooltip for Predatory Instincts is currently incorrect. This no longer works on Bear Form or Dire Bear Form and now reduces damage by 10/20/30%.” I’m going to assume that it still just works on AoE, instead of reducing all damage taken by 10/20/30%, because that would be insanely OP, as much as I’d enjoy my cat form having plate-level mitigation. And I’m not actually surprised they took bear form off of it, because I’m told bear tanking was simply too good in the beta. It does mean there’s no use taking it for tanking, though. More points for Infected Wounds or something, I suppose.
