It really did! It also says a lot that Land's Wrath is only learnable through the move relearner!
I prefer having it hold the Pixie Plate (which reminds me, that is the only held item that boosts Fairy-type moves? I would think they would have brought back the Polkadot Bow and make it work for Fairy-types).
At least Land's Wrath has
something to differentiate itself, a little. Land's Wrath doesn't hurt your partners in Doubles/Triples unlike Earthquake, so there's that, minor as it is.
just trying to look on the bright side I'm not surprised, though. Kyurem got the same treatment with signature moves, Giratina doesn't use Shadow Force all that often (it's still not a bad move, though), and Rayquaza doesn't even have a signature move (granted, he doesn't really need one).
Power Herb Geomancy is standard fare for Xerneas, though. It's easy to set up, and it's amazing to be at +2 in three stats so quickly as well. In contrast, if the opponent can force or phaze you out, then you've wasted your item, so it's not unstoppable. But both Geomancy and Oblivion Wing are fantastic signature moves, so I'm not complaining there.
