Certain rewards should be combined into a single unlock.
Shoulder pads - unlock shoulder pads once for both left and right shoulder, feels disappointing to have to grind through 2 levels for shoulder pads.
Emblems - emblem unlock gives you the weapon, armour and vehicle emblems. Emblem unlocks do not feel rewarding because they are not noticeable during gameplay and they have to be unlocked multiple times to have full use - see shoulder pads above.
Combining the above and putting alternative rewards in place of the consolidated rewards would assist with making the battlepass and events feel more rewarding.
