This thread continues to baffle me. Supposedly (I thought there was a source in the OP, but I no longer see it), all Sorcerers are getting Chaos Bolt. I'm just failing to see how people are leaping from "all Sorcerers are getting Chaos Bolt" to "all Sorcerers will be rolling on the Wild Magic table." I'm just not seeing the connection from Point A to Point B. It seems to me like a lot of people are jumping to conclusions.
I've also seen people equating this to all Warlocks getting Eldritch Blast, but it's a slightly different situation. Eldritch Blast is a Cantrip, while Chaos Bolt is a 1st Level spell. So, either CB will be changed from a spell to a class feature, CB will be dumbed down to cantrip-level potency, or Sorcerers will be limited in casting CB by how spell slot usage. If CB does become a class feature, we don't know whether or not it will resemble the spell that's currently in Xanathar's. They might change it so that the damage will start out as Psychic and then change to reflect the caster's eventual Subclass. Or it might stay as Psychic damage, with the caster rolling only to see if it jumps to another target.
