Tactical Rock-Paper-Scissors in D&D/TTRPGs

[Telok]

At the cost of drastically slowing down action resolution. Because now everything's an opposed "check" of some type. And that's super ultra slow once you have more than just a few combatants. Because instead of being able to roll 20 attacks at once and counting successes, I have to do the whole thing individually for each pair.

So like D&D then? Because it really starts sucking up time at about 10 participants in a combat. This is, of course, assuming the participants get meaningful reactions.

You see it if you take a party of 4 vs a boss with 3 legendaries and 3 mooks. Four player turns can trigger up to 7 reacting rolls from the monsters, then the monsters can trigger 4 reactions with rolls plus any free/non- action reactions from the PCs which can also involve rolls. And of course some of the reactions can call for further rolls like saves or checks.

Heck, a system with a single opposed attack a turn and nothing like lucky hasted battlemasters & counterspell chains could be significantly faster.
