When attempting to bring teammates with as Dynamo, Double Clicking to use the Alt Cast does not work when the ability is set to Quick Cast. I played around in hero testing with a friend and no matter how quick I clicked (set the allowable time as high as possible) I could not get it to bring teammates. When switching to press & hold or middle-click to alt-cast, it worked as intended.
Haven't had this problem with things like Bebop Bombs, Viscous Cube, or Seven Stun, and I think it's because those are targeted abilities, so if it doesn't see a target it will "wait" for the double click. Because Dynamo 2 can just fire instantly without targeting, it seems like it doesn't "wait" for the second click. As a result, I'm not sure if this resolvable, but Dynamo 2 should probably always work with middle click in order to make it possible on all control configurations. Alternatively, the ability to set just Dynamo 2 to regular cast would be helpful.
