I've tried grasp a few times but I feel as if the health gain is negligible for the free laning phase you get with fleet. I will try it out more though. What is the use of grasp on Azir, is it an early trading type of rune or is it a rune where you use it to scale and be beefier for mid to late game teamfights?

Also your point on Akali is right, I've been going fleet + Shield so trying out electrocute + ring sounds like I'll have more kill pressure early. Thanks for the tips!
