Windranger Core: Crit's the way to go

If you haven't seen Pajkatt's performance on Windranger, you need to check it out: https://www.youtube.com/watch?v=6V2v9KmDzmM. With three items - boots, aghs, Daedalus - dismantles Navi. The announcer (Purge) is pretty sold on this being better than boots, aghs and maelstrom into mjolnir because the damage is bigger and it isn't thwarted by BKB. I agree with Purge. Even though Alliance did have the minus armor strat going, watching a Windranger kill the Wraith King in 4 shots was impressive. Pajkatt credits Slasher at the end of the match for the idea. You can watch Slasher's guide here: https://www.youtube.com/watch?v=eNe7XmGiWNE. The basic idea is to rush aghs to remove the physical damage reduction from focus fire and boosts your survivability. From there, crit provides the solo kill potential that chain lightning lacks. Is this the best way to play Windranger? Pajkatt's performance makes a strong case for yes.
