The introduction of CDR and spell lifesteal talents make Blademail very broken. Spell lifesteal makes heroes either very tanky or unkillable depending on the lifesteal percentage when activating Blademail, and Blademail has a fucking broken 4.5s duration. CDR greatly reduces Blademail downtime, making it almost always available on some heroes. I think Blademail should be nerfed. The concept is powerful enough, it's the core item of Axe and Legion, and synergizes greatly with CDR and spell lifesteal. Its number should be low.
