So, this sounds like it actually should be this way but the problem is that you will keep on being in the reload animation while casting your ult. This only works if you don’t have a target to ult in front of you. If you reload and then spam your ultimate button echo will swing around her hand a bit, if you then keep spamming your primary fire you can make echo’s hand go up and down, blocking the primary fire. It requires you to actually keep pressing the ultimate button this whole time. I also made an imgur video (just type imgur .com with /sc4TTse) but I couldn’t include links.
