From a competitive-ish point of view I can see it as:
Crew already knows what it has to do, the captain makes sure they are not confusing priorities.
Hardcore communication with ally, to the point where you know everything that is happening on his ship. Map and killfeed help at telling you everything that your ally doesn't mention. An example of communication is telling him that you destroyed some enemy's balloon which helps your ally know that he can get out of danger easily, if he needs to.
Know the enemy even better than your ally. Again, map and killfeed, but the fact that you are actually looking at the enemy in order to outmanouver him helps knowing more what's happening on their ship, than on your allies.
Praises effort of said crew
Before I was competitive, I once asked my engineer dude, who always engineered for me, if he would want me to say "good job" at the end of games. He said he didn't care either way, because too many people mention that. And because people have high expactation of Rydr I am not used to praising somebody for their effort, more often than not I am complaining like a mad man, but try to do it in a joking manner, so the mood doesn't get brought down.
However, in dire situations I do throw out a thanks when somebody snipes a Hades when we are losing a sniping duel. Sometimes I even thank the Artemis engineer for destroying the enemy armor so our Hades can kill it. That doesn't make sense? If the Hades can't destroy the armor, somebody else got to do it so you can thank them for doing the job better than your Hades.
