This isn't going to be a "change the entire game" thread, but a thread on little improvements to the open beta build to improve the game.
1. This game really needs a multiple weapon/clothing sell/dismantle function. Tick/select all the weapons you want to sell/dismantle and press one button to sell/dismantle the selected weapons/clothing. It takes so goddam long to sell/dismantle 20+ weapons, when all you want to keep is the best assault/smg/DMR/sniper/LMG you have and sell/dismantle the rest.
2. On a similar note, buying consumables from the shop. You can only buy one item a time, it takes so long. Put a Fill Stack button on so if you have 1/5 C4 charges, and want to make to 5/5, click fill stack button to go from 1/5 to 5/5 straight away instead of buying 1 c4 at a time.
3. Public Matchmaking, give an option to matchmake with other people with a similar gearscore to yourself. I don't want to be level 40+ gearscore and join a guy who has just started the game and is on the 1st mission. There are times I might want to help people out, but there are times I want to group with people with my gearscore +/-10.
