+1 for different animations instead of always dodging.
Why else could a deflection event be good?
- "On hit" properties like Reeling could trigger logically without having to always do damage. (This would be too complicated for tabletop but not for a video game.)
Sounds like you're arguing for Touch AC here?. You're saying that rolling a to-hit between their Dodge AC and Actual AC could inflict Reeling, correct?
Interesting idea, but this would open up a huge can of worms in 5e. There are a lot of other abilities that it'd be ~reasonable to have an effect "upon touching the target" even if you don't get past their armor. And we'd be trusting Larian to properly balance this homebrew...at the very least this would exacerbate the "too many homebrew (and regular) conditions" that we see currently in BG3, especially as prone still inflicts unconscious = loss of concentration.
