Hey Riven mains, I have a few questions about Riven's build path:

1. When is it better to rush Axiom Arc vs. Eclipse as a first item?
2. In the games I played, building Black Cleaver didn't feel like it had much impact. Is the item actually bad on her right now, or is it just a me problem? If it is strong, when should I actually buy it?
3. Spear of Shojin stacks and increases damage on passive and abilities. I know it doesn't give CDR anymore, but why is it still not viable in her build?
4. Against a team with a lot of healing and tanks, should I go LDR + Chempunk Chainsword, or is Mortal Reminder enough on its own?

I've been playing a lot of Riven lately, and I see situations where I could run a crit build. In this patch, what's the full crit build for Riven?
