My first suggestion would be to have a more fleshed out profile menu when you access it. Rather than showing only notifications and what kind of missions are available for you to complete, introduce something ala DotA 2’s player profile menu. For example: You can see your favorite squad, most merc played, most proficient merc etc. These examples don’t sound like much but I’m not going to list every single thing that can be implemented, you all have grand imagination I’m sure of it so you can devise it however you want. I do not think this is something that will be gamebreaking and should be added just something I would like to see and I do not see the harm in it.
My second suggestion revolves around giving players some kind of positive credibility points for reporting people who are actually hacking. On the other side you would get negative points for false accusations. I was just thinking about this addition because there are people who get their asses handed to them by players who are really good. (I myself fall into the whooped category 
) With the addition of the ‘report a player’ option people who are getting whooped think that players who are better than them must be cheating/hacking. If people at SD check every single report this suggestion isn’t something that’s needed. I don’t know if something like this could help the SD people but just something I came up with.
For my third and final suggestion I would like to see an option of selling mercs for half the price or even lower than that. I’ve stated that from this introduction the players can benefit. I have some buyers remorse regarding Arty and I don’t want to have him in my roster. Don’t want mercs who I know I won’t play just sit there and gather dust.
