@Riot, Please Buff OhmWrecker and Banshee's Veil!
Right now, basically no one buys them because they are incredibly slot inefficient. Make them give 500 health instead of 300, even if it means making them cost 2900 like all the other major tank items. We don't care if items are expensive as long as they are good for the price. Look at Trinity Force and Rabadon's Deathcap, we still buy them because they are incredibly slot-efficient, even if they are the most expensive items in the game.
