Banner of Command was even stronger on Heimer before if you could manage to hit your stun and stay safe for a while. CDR and AP are what Heimer needs the most to put the turrets and have the empowered ulti available
The new Banner of Command make him more useful to the team by just staying alive., but no, as dmage the old was way better on Heimier
P.S. This new banner of Command means the death of Locketof Iron Solari...I mean, Locket of iron Solari can just disappear as Banner of Command is just flat out much better, could they finally rework Locket and make it an armor item like it previously was?
