Commander
If you’re talking about the Edge of the Mists specifically then I don’t think your class or race matters. The important thing is that you know what order objectives are likely to open up for capping and how to get from one to the other (including shortcuts like the wurm).
If you’re in a situation where you’re not running with a large zerg group then it might be relevant, but in eotm the commander is basically just a moving signpost saying “the zerg is here”, it doesn’t matter who that signpost is as long as they’re with the group.
“Life’s a journey, not a destination.”
Oh, so I asked question in a wrong way so here comes misunserstanding. Sorry for my poor English.
I was asking what class/race fits commander best. Like: for me it’s chaar guardian, because they were born to fight, bla bla bla..
So it’s just a matter of roleplay opinion that your asking?
