Could you please stop with this playercard shit please?
1. Please stop swearing. Learn to speak without disgusting expletives.
2. A playercard can be a strong indicator of a player's understanding of the game. It's not a guarantee but if someone has hardly played as one or another faction then it is unlikely he doesn't understand the faction very well.
I understand you don't like it because it suggests your arguments are not well balanced.
The more balanced the playercard, the more balanced the argument.
