I find the weapon selection part a little tedious when a long list of similar weapons is displayed.
I would think it advisable to add a filter of:
-BR - Only make Br I weapons visible for example (I have already made the mistake of using Br II weapons without realizing it for this reason and thus increasing my matchmaking Br).
-Due to the level/stars of the weapons - it is also another thing that I find searching tedious.
…and speaking of tedious… I recommend adding a preset for perks, just like you do with weapons, being able to save a perk preset…
lvlup them one by one for each soldier from all the squads, and the ones I am changing/buying seems extremely tedious, a preset would be a blessing.
