That Shaco Change on His E We Were Promised
Was in early S4, and I was told it was the current #1 priority. Was also promised an awesome ultimate buff that still bears strong similarity to the current R.
No such changes have yet occurred D`:. Rito, pls? Just played him, and he's still a shtload of fun :c.
PS. His E is currently maxed first, so whatever you replace it with should probably still be his "Max first," skill. His Q/W, even if buffed, would be poor candidates for being his priority skills because one is utility and one is a preemptively set trap, and he's supposed to be a dangerous jungle assassin whom can, y'know, gank well.
