And I think that's a poor idea. I like having the ability scores for the creatures. I always wondered in the earlier editions why they didn't have a full array. Again, this is one of those things that's easier to ignore or remove than it is to add.
Pretend this is a piece of paper on which is written the following:
Bob:
Tom:
Dick:
Harry:
1:
2:
3:
4:
etc.
At the beginning of the fight, everyone rolls initiative, and calls it out when you call their name. As they do, you jot it down next to their name, like
Bob: 14
Tom: 19
Dick: 3
Harry: 10
For bad guys, you can divide them into groups, or individually (I prefer groups and bosses)
1: 10
2: 10
3: 10
4: 10
How is this particularly time consuming or annoying? No arrow drawing (?), no "What's your Dex?" It takes about maybe 30 seconds to get initiative. Maybe a minute if I decide to light up a smoke while doing so.
