WIth the current state of the game where most games dont go over 30 minutes you dont get much value from Gathering Storm [29 AD at 30min]. On the other hand you can get Eyeball collection which gives less AD  but is also much faster to finish. For the Ultimate Rune you can either get Ravenous Hunter or Ultimate Hunter. I personally love Ravenous Hunter because of the Omnivamp it provides, pair it with Legend: Bloodline and you should be able to outheal the damage the enemy laner deals. Ultimate Hunter is nice too since it lowers your absurd ult Cooldown, 25% at max stacks + 30 AH [23% CDR] from Navori Quickblades reduces your ult Cooldown to around 85 seconds [67 at max level](can be even lower if you get another AH item/Blue Buff or Cloud Drakes] This works very well with the buffed 60s CD Galeforce since you will be able to do your R>E>Galeforce combo every 60seconds. Opinions?
