At the moment, I usually team up with N/Me (me is a Me/Mo) for PvE and we do talk about some strategy and take time to prepare - picking skills that complements one anothers. We tend to suggest skills to consider taking, rather than
tell/demand one another what skills to take. We know our own character's profession/setup better. Also, agreeing to allow each other to have the final say on our build helps as we're not setting off with any tension between us. If things do go badly then we know to listen to the suggestions next time.
Apart from preparing skills, when we encounter a group of foes we also spend a little time to prepare for combat. For example, (atm this really relates to charrs as we're just doing the Piken Square quests)
1. Identify what we are up against: bows, melee or spellcasters;
2. Identify if there are any patrols nearby, if yes then will they jump us from behind?
3. Decide whether to steam in to attack them all or use hit-and-run tactics and try to split the group;
4. Do we focus on one foe and take it down together quickly, or take separate foes. Whichever, we always call our target(s).
5. Specify the kill zone, where will we try and stand our ground;
6. Specify a fallback area. If the battle goes badly and one of us have to retreat, then this will be the place to go to heal up and recover energy. This way neither of us will run off too far and leave the other up sh!t creek. And if the other decides to retreat shortly after, then we'll be at the same place with a new kill zone.
During combat we're always communicating, giving the status of our target, our own status, calling new target and so on. Even with a prepared plan, it certainly helps if we know what one another is doing during combat.
This might seem abit OTT to some people, but hey, still new to the game. For a N/Me and Me/Mo partnership we ain't doing too bad. We may not have the prefect or even great builds, (still experimenting and trying things out - it's part of the fun and adventure.

) and having some sort of game plan certainly helped in combat - we both know what we're doing and what is expected of us.
Also, I do find the pre-combat planning enjoyable, it helps take away the mentality of just storming mindlessly into every mob you come up against, and pointing and clicking away mindlessly.
