Having only played DirtyBomb since yesterday, here are just a few things I fell are missing.
-Reading your loadout while in lobby, or even seeing the full profile while in lobby
-Ranked play for those in clans or in parties
-Countdown for joining a game already in progress, not able to choose which loadout or merc you want when joining a game
-attachments for weapons and loadout rarities; ex: loadout 1 is common, loadout 1a is a common but the best common since it comes with increased weapon magazine, or stability, or scoped sight attachment.
-*character skins: I know each loadout comes with a different color scheme, but I feel that would be better for level progression rewards, I was a big fan of Brink and I would love to see that level of character and weapon customization come to dirty bomb. I understand that is a bit out of this games core, so even if just adding a few different aspects like tf2 with its hats.
