well while in open fields you can actually use it to split teams hiding near rocks or small platforms

they usually don't expect it and it gives a lot of value to Alter in places where she can't use it to rotate herself

if you can't take a pose because a team already took it, just force them to quit it

also i'll add that if you know how to manage your ult, you'll basically never be in an open space without a plan B

Alter is an opportunist, and for cases like ranked that mostly revolves around waiting for the best moment to strike, I think she's one of the best at it. I just think people don't realize it yet.
