Gravity isn't really required for almost any other element - which is part of what makes it the overall worst element in my opinion. Earth's weapon can use it - and there's just about nothing else.
Yeah, absolutely nothing else. Too bad decks like Guardtal, Swallow, Cata-Titans or DBH are never-used, overly bad choices no one would ever make. Not to talk of Shard of Focus, a card so drastically underpowered without any synergy. Oh, and Voodoo Bravery works so much better without that unnecessary Gravity Pull in it.
