You literally have to be standing on top of them to hit them with it. 9 times out of 10 by the time you powerball into someone and hit taunt they are already out of range, perhaps due to the little bump that powerball provides. Maybe think about taking the bump out of powerball or upping the range on taunt to account for it.

you arent doing it right, keep practicing and youll see its best the way it is

I never had such problems :s

When you're gonna hit somebody with powerball, keep right clicking towards his direction to move right after the impact. Since powerball slows for a couple of seconds, you can easily get close enough to taunt him right after.

Care to enlighten me on the right way? How do you keep them in range for a powerball + taunt combo?

well seeing as how you have to make contact with powerball just slide your finger to taunt as soon as you hit, if you are by some chance out of range move up while they are slowed.

on another note powerball knocks up multiple targets so taking that away for the sake of a longer range single target cc would be a huge nerf.

Just use the hotkey--it's essential to use them at higher ELO's anyways. I can easily land a powerball, go into defensive curl, and then taunt someone before they are out of range.

Ok, some were under the impression that I was mousing. Nope I'm hotkeys all the way. I guess the main reason it fails for me is that the hitbox is so big with powerball that as long as it's the champ I hit directly I'm ok, but if I even graze the outside of a minion it's enough for them to get away (even though it snares).

So many champs have run speed boosts that the snare is no guarantee that they're in range long enough to taunt, unless I'm right on top of them.

Taunt is the only reason Rammus scores anything at all. Taunt plus curl plus tremmors usally does them in and if they escape powerball taunt again. I dont think the range is to short you just need practice when you see them comming in move in also. Of course if your playing against a good ranged dont count on it unless you powerball to them if thats what your talking about.
