To be fair, of all the spells in 5e that could use a buff, Witch Bolt is pretty high on the list. I'm not saying that I agree with how they buffed it, but at least this isn't a case of buffing an already strong spell... *cough* Flaming sphere *cough*
Agreed with most of this. I want to playtest Witch Bolt before I develop an opinion on the change.
