I took them all because, well, for what purpose a beta if not to test?
That said, the enchantments are largely too weak to be worth it, teleport is kinda broken, even at 16 mana, with the global pool since I can teleport to an enemy army and still unload on them, Terraforming is kinda pointless right now, and Combat seems like the best one to start with since you can grab Enchant Weapon and go to town on early mobs.
That said, like all of the things that you can pay creation points to start with, they're generally not worth it since you can get them in game, and there's plenty of great stuff that you can't grab later being offered.
