which B Ike?

I have +spd -res and I really like it. He doesn't need to get doubled by the enemy to proc Aether, because Urvan already lowers it's cd by 1, so the spd boon pushes him into a safer territory when tanking melee heroes and some dragons, because he will trigger Aether in every encounter where his qr procs as well and he will receive less dmg overall thanks to not getting doubled that often. The lower res is not really an issue because Ike is a melee tank and has no reason to stand and tank magic.

I'd fodder +spd. His spd isn't good, and thanks to Urvan and SB he likes to be doubled to charge Aether quicker
