If I could ask about any recommendations, it would be related to tattoos. Would there be a way to hold occasional competitions for fan created tattoo models that could actually be implemented into the game? Other games, like Warframe, hold skinning competitions for their community. I think with the large community Ghost Recon has, it would be very cool to see some additional tattoo designs. If these guys are military, possibly some branch specific ones. Or some tattoos from other countries the Operators may have visited at some time in their past careers. Add a little more community interaction with some skin options.
So, possibly hold a competition for branch inspired tattoos, then take the top 3 of each military branch and/or federal agency (FBI, CIA, etc...) and let the community vote. Get some nice tattoos added in. (Fan provided content is free to you!)
Will there be a grappling hook to get from point a to point b by shooting it towards a roof or other object and then ziplining down? Will there be any city centers with skyscrapers and interiors with grappling optiona (ala. RS Siege)? Will there be buildable cover (would be cool for a mission type like embassy defense)? Will there be gas based weapons or mortars? Will there be trains or any other vehicle types (planes, boats, mountain based gondolas)? Are there any skills for sprint speed modifiers, quicker ADS, etc.? Is there the ability to call in UAVs, air cover, or other ancillary support? Will there be multiple varied mission types like protection of assets, target assassination, etc.? Will there be more gadgets than just the drone also is there the option for a ground based drone as a nod to RS Siege?
Just a few off the top of my head. I'm really excited for the game. I can just see it getting very samey without some of these features.
