Nope, the sooner you capture a command post, the sooner you're team get's its bonuses. Rushing towards objectives for xp is great, better than camping for kills.

Even if I knew the maps like the back of my hand I'd still use objective wheel for communication purposes.

Agreed.

There are no real game modes specifically. How it basically works is you play the campaign, in the multilayer. It's almost the same thing. Only instead of being against bots, you are against human players.

Rather interesting, I'd like to know which objectives you would use the objective wheel for communication because I personally can't think of a single objective I would do it on.

Say you're a medic and you decide early on that you want to escort the civilian that is one of the main objectives for the map. If you use the objective wheel early, you would allow soldiers to take the "keep medic and civilian alive" mission, so that they would know to follow you. Even if you say it, the fact is that having the mission available to soldiers would be much more effective in a pub.

It would also tell the other medics that you are going for that objective. This is important because then the other medics on your team can go revive downed teammates. If you hadn't used the objective wheel, however, you would most likely have 2 or 3 medics going to save the hostage and no one to revive team mates.

You're view on medics are a bit off, medics are always (In most cases) at the primary objectives because that is where the action is, that is where the medic is needed to support his fallen / injured teammates. They are not wandering off to the edge of the map just to revive one player (That will never happen because the player is more likely to tap out and go into next spawnwave) .

Medics will be around the primary escort quest objective, because that is where they are needed, that is where your teammates will die. How the escort objective itself is working is a bit hard to tell because I haven't seen how it works yet.

XP grinds are the main objectives. The more XP an objective gives you, the more important the mission is to the team's victory, so you want people rushing towards XP grinds as that is the team's target.

And there will always be those players who see someone else getting there earlier and either say "Alright, he got it, I'm outta here" and search for the second best objective, OR wait for that person to get steamrolled by the enemy team (if there is enuff time left) and then try it again on their own.

Atleast they go for the objective. And he'll get steamrolled as well.

But if that person sees another has an objective under control, he should go for the second best objective, as that helps the team out as well; not as much as the main objective, mind you, but it helps out. And the person wouldn't wait for another to get steamrolled, he would defend him, earning extra xp for killing enemies near an objective.

Another argument for using the objective wheel for communication. When you're a medic, if you take the mission to try to revive someone, they will get told via canned chat that you're on your way. That way, they will know not to tap out for the next respawn wave. Irrelevant for players that have a mic, but on the PC a lot of players don't. If you end up getting thrown in a game with international players, though, then canned chat suddenly becomes useful once again.
