Hopefully this is the last fix:


 * Attack range reduced to 150 from 250.


 * Ultimate CD increased to 150 / 130 / 110 seconds, otherwise unchanged:
 * It isn't necessarily a guaranteed stun- if enemies walk away from the center, it wouldn't pull them in faster than 380 (about average for movement speed 2). Doing an R-W combo certainly applies a lot of Sandstone stacks, but only enemy units caught in the center of Whirlpool would face the stun.
 * Also, casting W in the R stops ALL damage from the ultimate, and enemies who are stunned by W are no longer affected by it: stunned for 1.5 seconds and dealt up to 150 true damage, then free to go. Thus, the only other way to stun an enemy is with Q, and only if they are fully stacked. Plus, have a look at 's ultimate. At 600 AP, full duration would do just shy of 3K magic damage- and this area can move with him.
