I have defended balanced talent speccing. I remember the rant. It can be a good choice while leveling. This game is huge! Sometimes, when one has figured out an aspect of it, they will infer greater understanding than they actually possess. The many nuances of the game allow viable builds that will augment different styles of play.

Balancing can be a very effective way to play. Don't bother about rudeness, it's a weakness we all possess. It may indicate a weakness in their views. If you gave them no cause, there should be no concern. Just worry about your own actions.
