"Deadeye"'s Vi teaser was unnecessary
For the past week, "Deadeye" has been an itch that we've been unable to scratch. The Zed part piqued our interest, Sona made us insanely curious, by the time Garen had his bit it had gotten kind of old, and now the Vi one is kind of a middle finger saying "we know you're dying to know about this, but we're gonna give you FOURTH teaser just to piss on you."
Vi and Garen should have just happened at the same time, at this point it was just unnecessary and only prolongs the waiting.
