Sparkle powder nearly caused a seizure. PLEASE do something about it.

As I feared, the sparkle powder that is now all over the game is not a good thing. 

I was on the Fleet tonight, minding my business and giving gifts to a companion, when several players surrounded me and threw sparkles. I could not click the buff away and within seconds I was feeling queasy and lightheaded from the flashing lights. I had to click away from the game window for several minutes. 

I get it, some players find it very fun. Others like me find it very dangerous, especially since it's something that can be thrown at my toons without any warning. It's not something like a boss or a specific area I can avoid. I don't even know how to avoid it now, other than to completely avoid the Fleet, avoid non-instanced areas altogether or stop playing the game. 

PLEASE add some kind of buff or 'vaccine' that will allow us to reject the sparkles. That way, those of us who find them fun can still enjoy them but those of us who are susceptible to seizures or other problems from rapid flashing lights can stay safer.
