The new Major Crime negotiation system is good and I think we should keep this change, it keeps those who are looking for RP and those who are looking for combat happy as they can just call off negotiations or actually negotiate.
The new reporting system I think is more inconvenient, I prefer to be able to just report someone for something they did there and then rather than having to go onto the forums, fill out a report template and make my report, going back and forth waiting for someone to reply can be annoying where as in a voice channel you can get your point across much easier and get the situation dealt with much quicker overall.
