Is Gale canonically an abjurer? It lets you pick his subclass for yourself.
If counterspell is a thing, and they may be incapable of implementing reactions so it may not be, it will have a major practical effect.
I've been thinking about this a lot lately. Could you imagine counter spell in the current system? You would just auto counter the first spell that goes off. If it's like hellish rebuke, you would even have to spend the spell slot BEFORE you cast it, which is gross.
Even worse is the divination wizard's portent ability. How would that work in the current system? What are they going to do, nerf divination wizards? I hate to say it, but it may be the case.
