I was still interested on this matter so I contacted a SOE GM today. This is what the response was.
GM Endina here to assist you today. I understand that you have some concerns about using a third party program while playing Planetside 2. In general, we don't recommend that players use any sort of third party program while playing Planetside 2. As long as the program does not give players an unfair advantage, however, they are generally okay to use at the discretion of the user. Please be aware that if it is detected by our system or if it is determined that it gives an advantage, action could be taken on your account. If you have any other questions about it, you can always check out our official forums (https://forums.station.sony.com/ps2/index.php
), as there is usually information from our development team regarding this type of situation. I hope this helps, and have a great rest of your day.
Basically if it gives an unfair advantage it shouldn't be used.
Up to you to decide if that's the case or not.
