There are a lot of reasons to potentially delay your order in initiative. Waiting for the enemy to dash toward you, for one, or maybe getting a character in melee combat with an enemy so Astarion can perform a sneak attack on his turn.
That and it's very annoying when you're playing something like a wizard and your turn order is bad so all your setups like sleep and hideous laughter are all a turn or two off.
Maybe tie it into dexterity. Like if you have high dexterity you move faster so you get your turn faster than others. Then add a spell that buffs a persons dexterity by a large amount for one round of turns in order to boop them up in turn order and a hex spell that does the opposite for the enemy, but both spells can only be used like maybe once per match or they have a downside. Like you get more speed, but suffer a heavy defensive penalty for that turn.
