do listener make good conflict solver??

It is of my opinion yes, someone who is good at listening will have a better understanding of the situation. That is of course, they were actually listening and not letting information go in one ear and out the other. It shows disrespect, when someone is only hearing 1/3 of what's being said. However, you can't exactly expect listening to be enough. Making conversation, asking questions and making an effort to understand everything involved, makes a good conflict solver. Listening is only one tool required. Though the ability to comment and question shows actual listening, and not the in one ear and out the other syndrom shared by many.

Sometimes yes, but sometimes no. There are just a lot of times where listeners tend to be able to hear everything that you say and they are going to retain all of the information. There are just going to be a lot of times where they are going to be some kind of solution to say the very least. So they are going to rather just step up and find a solution. However just because they are going to listen, might not mean they have any better of a grasp at the situation than you do. Sometimes they might be able to find out some kind of solution but obviously not all of the time. There are just many times however where the conflict is something that even with all of the information and with a differing perspective, it remains baffling.

Good listening skill is just one of the requirements to become a good conflict solver. Along with this, I believe, a good conflict solver needs also these skills: 1) above-average analytical skill 2) critical thinking and ability to ask pertinent questions 3) thorough knowledge of the background of the issue 4) sense of fairness and objectivity 5) independence of mind 6) wide source of information on pertinent areas of the issue (e.g., labor, commercial or civil law, company/state policy, etc.) 7) good interpersonal and human handling skills
