I have no idea what to build in Season 6

Please redirect me to better builds to better improve. What I've been building since the start of pre-season Vayne: Stattik, RFC, Berserker's (Furor or Homeguard)-> Infinity Edge -> Death's Dance or Bloodthirster -> LDR, Mortal, Mercurial, or Banshee's Draven: Infinity Edge -> Bloodthirster-> RFC -> Berserker's (Furor) -> Mercurial -> LDR -> Essence Reaver Twitch: BOTRK-> Runaan's-> Berserker's (Homeguard)-> Ghostblade or LDR or Mortal (vs. Mundo)-> Infinity Edge-> Death's Dance,Bloodthirster, Mercurial, or Banshee's Kalista: BOTRK-> Runaan's-> Berserker's (Alacrity) -> Infinity Edge-> Mercurial, Bloodthirster, Death's Dance-> Banshee's, Maw of Malmortious, or Frozen Mallet. Tristana : Infinity Edge -> Bloodthirster -> RFC-> Berserker's (Homeguard or Furor)-> LDR or Mortal -> Mercurial, Banshee's or something like that

Can someone explain the changes to Ashe? Does she no longer do bonus damage on crit instead getting a double slow?

Also, new builds for Diana and Elise jungle would be nice. (AP bruiser and AP assassin for Diana, AP bruiser/ tank for Elise)

I'm sorry I don't play Quinn, not enough IP QQ. Been using it on supports and junglers QQ.

Oh yeah, can someone show me a Morgana support build that lit works. Been trying pretty much everything in existence.
