Honestly, while I wont complain about giving Destiny a buff, making both classes count as Main definitely seems nice. I feel that it's perfectly fine right now.
The additional Skill Points make it appealing for those whom wish to broaden what skills or spells they have access to.

Although I will say that I have 5 characters that are Destinied, 2 Curates. 2 Soldiers, and 1 Mage. So there may be biases in opinion depending on which classes are worth Destinying into.
