Only if this reactions work like in Xcom, where they only work with natural attacks- in Bb3 in the form of cantrips. They trigger automatically and you can not interact with them in any capacity.
Most notably: overwatch: would become readied spell: you use a selected cantrip that is in your first slot [first pick at char creation]
Sorry, but are you saying that we should only be able to ready a cantrip? And we don't actually get to choose which cantrip we're readying in real time? I strongly disagree. You should be able to ready any spell that has a casting time of 1 action. At the very least you should be able to choose which cantrip you're readying. Firebolt for damage? Ray of frost to reduce enemy speed?
This is getting a bit off topic, as the thread is supposedly focused on a Ready Action system, so I'll spoiler the following about reactions.
- on the note of solasta reactions, they are really annoying and make combat disruptive by ruining my Emerson by constantly clicking yes / no. It should be automatic and without control on player part- because by logic, reactions are our impulses. You can’t control those, it’s done by our fight vs flight response.
1.) Did you have a Paladin with Smite and/or a Sorcerer with Metamagic on your team? If so, then yes I agree that the amount of pop-ups does become a lot. Do you think you'd have liked the system if those abilities didn't show up on pop-ups? I'll not that neither of those abilities are reactions.
2.) You suggest that "reactions should be our impulses, and thus it should be automatic." Why is this incompatible with being able to choose, especially in a TB game? By that logic, combat is hectic and since a round only lasts 6 seconds, you should only have 6 seconds to choose all of your abilities. If an opponent walks past your character, yes they only have a split second to actually make an attack of opportunity. But this has no bearing on whether the player should be able to decide or not. Deciding "yes vs no" can be a split second opportunity, and taking that away from the player means you have less control over a character you created to play as.
