Thanks for the advice so far! Does anyone know if the haste effect from the arcane bloodline counts as the actual spell? If so, would I be able to take mythic spellcasting and spend the surge to make the haste effect mythic?
Hooooooooly moly, I hadn't seen mythic vital strike. To be entirely honest, I'll check with the rest of the group, but I'll probably give it a miss, that damage would be absolutely INSANE. I was thinking of taking impossible speed and fleet warrior, coupled with taking the barbarian rage power "come and get me" so I can dart into combat (slicing every enemy once from the attacks of opportunity), slice one guy to shreds, and then run away quickly. Admittedly, vital strike would be perfect for that, but I'm pretty leery of the damage that single hit could do.
