Saving collectibles

[NADIE]

Are the collectibles worth saving until level 30 or 40? or are they not even worth it?

Alright what do I mean by this?
In the first game from level 1 to 29 collectibles are worth 300 exp when you pick them up but the second you hit level 30 they are now worth 110K exp. At level 30 you need 400K exp to get a field proficiency cache meaning that if you saved up the collectibles every 4 collectibles you are getting a field proficiency cache.

Is there something similar in this game? I can see that every time I level up the collectibles are giving me more and more exp but it is still so little its not even worth it to pick them up.

After reaching level 40 I can confirm that collectibles are not worth saving up to max level.

They don't have an increase on exp after you reach max level like they do in The Division 1.

Up to you, but I wouldn't put too much thought into XP.
XP is very easy to gain in this game.

If you find a collectible, just grab it. Collectibles overall are not meant to level players up, they are more just like "hidden packages" in the game.
