Seeker Armguard!
Just thinking that most items have more than one build path, and I was thinking for Seeker's Armguard what if they had it build into an item for tanks that didn't have the zhonya's active, but rather just gave tank stats.
For Instance: The Armguard's passive currently stacks 15 AP and 15 armor. What if on the new item it stacked to 75 armor and 45 AP?
