Daily Punch 8-31-20 Attentive Fighting Style for DnD 5e

I miss the old days of 4e where a fighter could interrupt attacks on other people. Let’s make that happen!

Attentive

Each round as a free action you can choose one creature you are engaged with. If any creature targets your chosen creature with an attack and you are engaged with the attacker, as a reaction you can make an attack on the attacker.

Thoughts?
