You make a good point! Unfortunately many players seem to think that these challenges will unlock something that will help them and that’s simply not the case.
If more players knew that completing challenges offered no actual reward then they wouldn’t worry about them and wouldn’t leave matches nearly as much. For some reason the majority of players seem to think the various “armor” has a purpose when in reality it does nothing at all.
If everyone ignored the “armor” like I do this issue wouldn’t exist and the game would be in a far better state.
You only had to scroll up a bit to find the answer you’re pretending to be looking for, but just for you I’ll quote the post. Don’t forget to thank the person who posted it!
