They got replaced by the now monthly side quests
I think they need to bring these back, but they need to be SERIOUSLY scaled up. The first one I remember was the Coulson challenge. It was designed so the most players wouldn't finish it. I'd assume that less than 5% of the player base finished that challenge 100%. They were structured differently than the most recent ones. There were no portals originally. You had to do the whole thing in one go and there weren't multiple versions of the same fight within the same map. Personally, I liked this old style better. The last few we've had have been pretty easy so long as your account is older than about a month. Players are able to speedrun the final map without much thought. I'd love to see these make a comeback, but I'd also hope to see a serious challenge come of it. Maybe bring it with the same layout and reward structure as before so it's just as accessible as the last few times...but add in a separate Cavalier difficulty that's crazy hard with rewards to match.
They weren't a regular occurrence. Just an occasional treat. We've had Boss Rushes more recently, but in both cases, they're special content that comes once in a while. Having said that, I think we're due for a Challenge soon. Just not sure the team would have time. Lots going on. Lol.
