Consolidating object-interaction & bonus into minor seems reasonable & in keeping with 5e which did a lot of consolidating. And the downgrade path is a good idea in that it gives greater flexibility, and avoids making unrelated options incompatible as a mechanical artifact. Both more sensible, and returns to a more intuitive action-economy, rather than arbitrary opportunity-cost economy.If I had to change anything, I'd change Bonus Actions to Minor Actions and tweak how they work a little bit. Have object interactions be a minor action, allow people to downgrade standard action to move or minor (but don't downgrade move to minor to avoid things like casting a third spell in a round).
A fair amount of that was inevitable, I suppose.I think that would be a cleaner system and allow more flexibility. The name change doesn't really matter much, but to me it's more logical.
I understand why they did it, I just think it's more confusing than necessary.
I'm not a fan of breaking up movement, with the way it allows someone to come out from around cover to cast a spell and then return to that cover before anyone can do anything about it, so I'll just say that I prefer the 4E action economy in every way. Of the problems with 4E, action economy wasn't one of them.You know, I came into this liking 5e's action economy, but when I broke it down I find it inferior to 4e in many ways, with the only exception allowing movement at any time including broken up.
I like 5e, it's certainly cleaner than 4e or 3.x. You could say older editions were even cleaner - move and make an attack - but the trade-off there was you generally needed a lot of discussion and/or house-rules and/or DM rulings to work out exactly what people could and could not do on their turn.
