If you have 30 forge points I would just build anything you want, that will let you max out 2 attributes, or balance them out if you wish. That's what I'm waiting for on most of mine, but forge 10-12 is also pretty good if you want something in the mean time for weapons and characters that you like to play often, you'll just have to pick up another blueprint later.
After crafting at 30 points, I'll probably wait for 45 points (3 maxed attributes) to craft again, due to rising gold costs.
