I wholeheartedly agree. And, I'm not sure if Storm Raven means to take this one step further, which I do. I use prerolled initiatives. I roll inits for all NPCs prior to the session (more than enough, maybe 3-4 of them). I make the PCs roll inits for the characters prior to the session, given their default modifiers. They give me maybe 15-20 rolls, written at the top right of the card (where all the NPCs inits are written on their respective cards). Prior to any encounter I have the cards presorted.
When an encounter starts, there's no rolling, no shuffling, no sorting. It's an immediate impact of, "Okay, Verilia, you go first, what do you do?"
That undeniably creates the most interest because players have to act/react without pause.
If a player's init changes, I already know it because they would have had to inform me that they casted a buff spell (e.g. cat's grace), and thus I take that into account.
