What's your reason for doing challenges?

As a competitive and forge player I only ever focused on arena and forge. I never participated in any challenges in any game wether it be Apex or anything of the like. I see literally no reason to do them. I wanted to know why you guys do them

In my view challengs shouldn’t exsist. The only thing that should exsist is hard campagin challenges that get you exclusive armour you can’t buy. Aside from that. Maxing out battle pass or doing challenges is just something I never understood about gaming. Like who cares if you win 3 oddball games. Like what’s the point of that? Small little rewards that mean nothing?
