Commander tag
Having a blue dorito does not magically imbue someone with capability. There is not real way IMO to actually insure that someone is a good commander or not.
Some of my guildies and I followed a new commander around in WvW last week. Another well known commander was in the group and tagged down. He was very supportive as we all were of the new guy. You only learn by doing. He asked that experienced commander to let him know if he was making a bad decision. He didn’t want to get the group wiped. There were a few times that the other commander made some suggestions and one he just told the other guy, “Don’t do that. It will be bad.” he then explained why.
Everything the new commander did wasn’t optimal, but he tried hard and learned a lot. Overall, he didn’t do a bad job.
I think what makes a good commander now, is how much he is willing to learn from other people and his/her own mistakes.
Just thinking you know everything because you have a tag will come back to bite you in the kitten.
