Stupid interaction between Taric's E and stealthed champions
So... I just played vs a Twitch Taric botlane. Apparently, Taric's E is longer than Twitch's reveal range, and while Twitch is stealthed the dazzle ray is invisible. Why? I mean, I've got stunned and I didn't even know why until Twitch came out of nowhere and melted me.
I don't know if this works with other champions too, but it makes no sense that I get stunned by something that I don't even get to see before dying.
or 
to see if he's going to use Dazzle. If he goes & looks like he's dazzling thin air, either run like the plague or pray your support has peel.
for doing the same thing he does but to one person in melee range
