Whiling throw is pretty clear about how far you can throw.
Not so clear about where do you throw from.
This may sound like an edge case but the grapple focused clinging shadow stance gives you reach.
To be clear, I'm not talking about the cheesy vertical throw. I'm talking about what square do you count the distance from.
Do you:
Treat the throw as a long shove and move from the original position of the creature.
this is intuitively the safest reading but combined with reach, it ends up feeling more like a knockback than a "whirling" throw as throwing backwards eats up half your typical throw distance (15ft)
Treat the throw like a thrown object, and count from your space.
I tend to gravitate towards this reading as it lets you throw in 8 horizontal directions without difference which matches with the mental picture of a throw using centrifugal motions I have, it effectively reduces the maximal distance you throw away from yourself by 5ft
Same as second option but count from within your reach.
this is originally how it was played at my table until I took clinging shadows initiate and realized this gave me a lot more distance and flexibility to reposition thrown enemies.
As a clarification, I believe all three readings shouldnt affect the damage done, that's set in stone. My concern is mostly about how throwing backwards can make a difference of between 5 to 20ft depending on the method you use and whether or not you have reach.
I'm not sure that it really makes a difference in the game balance. At least not in an abstract sense.
Various specific scenarios would favor one ruling more and others would favor a different ruling. But to pick one ruling that gets printed in the rule book is pretty much a wash.
So, I guess, pick a ruling that your table likes and keep it consistent.
