For start, This list is full of my opinions.
If you agree or disagree, comment down and be reasonable.
Multiple grenades in a row cancels animation
You can Knife while running.. no animation + OP
Unbalanced games always 3v5
sounds while spectating.. (while spectating player, spectator hears players own steps and its very confusing)
QUE NOTIFICATION, (It could be something like grey box. just so it wont blend on background)
Que counter, timer to tell how long and how many players are in que currently.
Player animations are horrible…. i think that this is already on your list
Example of this is Q and E animations.
Guns are too close to face.
Running meter, show how long can i run from now on
Tell player what to press while being on bomb site
Starting countdown is too long
Bullet holes would be awesome
Remove scoping if player jumps while aiming
Recoil on snipers
create easy to launch server creation tool.
Work on skins/loot boxes after game works properly
Stay vague on patch/update/release dates because if those wont hold on, players get disappointed
Make small tutorial at the start
Profanity filter on chat
Make hud to show
Game launch speed
weapon models are well done
Game mechanics work
This list is not meant to mock devs or community, its just what i SUGGEST that could be added.
