Victoria Rules
Yes, that's what I'm referring to - do they use co-ordinated tactics or not. Do they work as a team instead of a bunch of individuals. (same can be asked of my game's PCs more often than not)See, now I feel like we need to decide what is mean by “team”.
Because my first thought is “They aren’t killing each other, and they all want to take out the PCs… so yes, they do work as a team.”
However, you could be referring to the level of tactics they use. Do the brutes shove their targets back into the dangerous terrain created by the spellcaster or do all the enemies rush in and fight individually.

Now that's something I hadn't even considered. Then again, if I'm a front-line banger in a group and someone claims an opponent as theirs alone (and will get mad if anyone interferes) I'm happy to leave 'em to it...and if said opponent proves too much and they call for help that help ain't coming from me.See, but you want that to happen. Your players probably don’t want to get in each others way. Now, I’m picturing different players than you are, my group is… well, I’ve actually seen people complain about kill-stealing and had people calling dibs on killing certain enemies.
So, with that in mind, if your players get into each others way, they might find a humorous situation out of it and laugh. Mine, are going to get upset, some of them really upset, and that isn’t the sort of drama I want at the table.

Sounds like your lot take it all far more seriously than us - 'round here if there's not laughter on a regular basis we're doing it wrong.

Unless one interprets the RAW to mean these things each happen individually on their additive die roll - so if a Rogue rolls three dice and gets 3 - 6 - 4 then the move happens on 3, the attack happens on (3+6) 9 and the bonus comes in on (9+4) 13.That isn't how it works per RAW.
RAW for these rules is you roll all your dice and do all your actions when your initiative comes up. So bonus actions can add either an extra attack, move or spell die to your roll and make you act later in the initiative.
This is why people are saying Rogues and Monks will now be more likely to act last in the turn, they often move, attack, and use a bonus action, so they will be rolling three dice most turns.
Howzat?
