how can this be adressed?
well, when somebody is commanding for the first time, you cannot expect an awesome result...
personally, i think it is very helpful for that person to be commander at least once as it allows you to understand the tech-tree and other aspects of commanding you might now have been aware of as "foot soldier". it might be a lost match, but the person might greatly benefit from the gained knowledge when playing as foot soldier again, e.g. it might improve the feel what the commander is expecting from you even though he is too busy to tell you in this situation. e.g. you will know that an advanced armory is very expensive, that it can be a waste of ressources to build an extractor too close to the enemy.
however, the majority of people seems to be heavily annoyed by this: comments like "eject this noob" and "omg its already over" are among the polite ones. but how will they be able to become decent commanders? playing as foot soldier will certainly improve you a bit, but i belive there are limits to this: at one point you have to give it a try. there are several games where nobody is commanding, probably because they are afraid of the negative feedback. even in those games the people get harassed after pushing themselves to do the job as nobody else is willing to. i think those people deserve some more respect. there is no match making so you cannot expect those people to win on their first tries and it's not like a win means anything in a beta without any permanent score.
so, are there any ideas on how to make the commander-experience more noob-friendly in terms of community?
