In 5e you can counter-counterspell a spell you are casting. What if that were not possible?
I.e. You cannot Counterspell the Counterspell that targets you or a spell that you are casting. You may still Counterspell a Counterspell targetted at another spellcaster or their spell.
Or, more generally, you cannot take a Reaction while you are executing an Action or Bonus Action when said Action is casting a spell.
To theory-justify this, it would be because you are currently casting the original spell and cannot be casting two spells at the same time.
What problem does this solve? It reduces complexity by limiting competing Counterspells.
