When Azir did Something Useful - Dominion
I just discovered this in a dominion game while messing around with Azir. If he uses Arise! to make a Sand Soldier, sends it out with Conquering Sands, and then uses Shifting Sands, Azir can move outside the spawn platform before the game starts. If he tries to move while off the platform, he will walk back into the spawning ring. I will have to try again to see if he is able to fully move off the platform to the normal ground, but if he is off the platform when the game actually begins, he can start walking from his location off the platform. This gives him an advantage at starting and could be worse depending on how far off the platform he can go. I'm about to give it another go to see how far I can make it out. But this is a glitch that needs to be fixed.
EDIT - I just tested it again and it seems you can only move to the end of the stairs using the glitch and no farther. You can still stand there and wait for the game to start which gives you an advantage over the people who start on the spawning platform.
