Very reasonable Illaoi change
Make W cause all active tentacles to swing in target direction, regardless of whether or not they're in range to hit that target.
Now she can create reasonable threat and isn't so easily cheesed by moving just slightly out of her range. Still easily outplayed by just paying attention to her tentacles, but punishes you for silly dashing around her or for someone else being a near tentacle when she's on the attack. Also dramatically increases her potential for plays based on positioning in teamfights.
Reasonable.
