Constructive TLDR: Please remove challenges that rely on luck in any way, and make the challenges reflect and reward player skill and direct impact achieved by the player.
Let’s narrow it down real quick - Challenges are probably here to stay.
With that in mind I find it really frustrating, that some of these challenges rely on pure luck, rather than player impact. Especially given the fact that these are limited time challenges (weekly/event) that actually offer a reward, so the incentive is there to grind and complete them.
To be specific, one challenge in particular stood out to me during this current event:
Dream After Dream - end an opponent’s killing spree
The sheer fact that you have a challenge that requires your opponent to play well, and then require that you end their spree, is just insane. I mean, the killjoy medal is cool and all, but to build a limited time EVENT challenge up upon something that you literally have no impact on what-so-ever is insulting.
It even stacks, so that if you swap the first one (0/1) you could be so unlucky that you get it stacked later on in the event (0/5).
In no way should it ever be possible to rely on your opposing team’s skill level and sheer luck to complete a limited time event, weekly challenge or free event etc. where there’s a reward on the line.
Challenges such as the shade-turret kills, gungoose kills and such, arguably have SOME direct player impact I guess, even though one could argue that the luck factor (map requirement and such) is unacceptably high as well. But the Dream After Dream challenge was pushing it way beyond acceptable.
