Agreed, I've always hated how vague and useless their tooltips are. It would be so helpful for players to not have to do homework on 3rd party websites all the time, just to get accurate information on how to put a build together. Every other game with the same kind of complex abilities and buildcrafting that Destiny has will actually tell you what your dam abilities do. Also just in case you were curious about what Omnioculus does, it provides 50% damage resistance to anyone you grant invis to (including yourself), and 50% of your melee energy per ally you make invisibile. You can find all the detailed info that Bungie should be giving us themselves on a community made Google Doc called the Destiny Data Compendium.
