Steph, like the others said, edit the screenshots or else you will be banned for Naming and Shaming. Reading conversation, makes me realise how lucky I have been the past 3 years.
We should be glad that we do not have a bad commendation. If we had this feature, players would use it for the wrong reasons. I can already see the reasons for giving someone a bad commendation.
Players will give others a bad commendation, because:
1. They are trolling their party members, so they give them a bad commendation.
2. Players do not live up to the standard of certain players, so they give them a bad commendation.
3. Giving a player a bad commendation, because they got the item drop that you wanted too.
There are more reasons, but one can understand why SE has avoided this. Yoshida was once asked why they did not add this feature and he basicly replied that players would use it for the wrong reasons.
