Azir and Braums Passive
When using Azir with an ally Braum you can't stack Braum's passive if enemy units are within range of Azir's soldiers. Azir himself can't attack enemy units while they are in range of a soldier, only his soldiers can and Azir's soldier don't stack the passive.
I don't know if this was suppose to be this way or not, I just noticed that it makes it so Azir cant help lock people down in fights when Braum's passive is trying to be stacked.
