Can someone tell me how exactly the Challenge Rift works on season start?
Can you somehow complete it just before a season releases, or are people (that talk about blood shards on level 1) going to take the time to do the Challenge Rift after the season begins? Because in that case I'll prefer to just jump straight to leveling.
You create or rebirth your seasonal character first. Right after, you do the Challenge Rift. Then you start leveling.
