You've basically taken Greyhawk initiative and reverse engineered older forms of initiative which were very similar (although it's hard to say whether what you describe is exactly the same as any particular edition as initiative was often confusing and usually houseruled in some way or another..I don't understand what either 'all the way' or 'spell interruption' means here.
I like to think of it as a fully formed and implemented houserule (really a heavily modified Greyhawk Initiative) if that is what you're asking.
One of the key components of early D&D (although often ignored to the games detriment) was the possibility of interrupting spells. This to my mind is a the most important aspect of having the declaration phase. You declare a spell and then if you get interrupted before then and take damage you lose the spell.
...We have found that having the group all decide on what they're going to do at the same time speeds up the game. The resolution of the round goes quickly as well which feels cinematic....
I asked you a question based off the similarity to earlier editions. You were confused about the question so I explained the context and how historically declaring spells so they could be interrupted was considered an important feature of a declaration phase.No, declaring actions isn't 'readying' them.
The characters do their actions on their turns.
I guess we use the declaration phase differently than you. That doesn't mean we aren't going 'all the way'. Our system is complete and works well for our purposes.
To be fair, by asking "did you go all way," has in implication of incompleteness which has a negative slant. @ad_hoc probably felt a bit attacked and didn't like the tone of your question. You may not have intended it to be an attack. but as a neutral 3rd party here I can tell you it can come of that way.I asked you a question based off the similarity to earlier editions.

If you don’t like the idea then for gods sake don’t do it. Make’s no difference to me. (And it’s a big departure for 5e anyway.)
Not really seeing any justification for the tone of your reply.
Rolling every round doesn't change any of the terms, but it may get you some funky results every once and a while (as you noted), but that doesn't seem like to much of a big deal. Alternately, just changed it to rounds. And everything becomes "end of the round," or "end of the next round," or "in 1d4 rounds" or whatever. That is very easy to implement on the fly, I know from experience as I to prefer it to "at the end of its next turn" sometimes.
I just don't find that to be the case. D&D, and 5e is very flexible if you are flexible. We've been screwing around with it from the beginning (our latest is to use 4e powers) and it hasn't messed things up. We just keep on rolling.While 5E is less problematic, it is very tight balanced around it's Initiative, action economy, CR system and per short/long rest mechanics. When you start screwing around with all the spells, PC abilities, monster attacks, changing how initiative works, etc, what's the point?
