However, if you skip the Ed. the other rewards are all very achievable with much, much less effort.
99.5% of the player base will be excluded from the top Event reward as-is, but 99.5% of clans should be able to get at least a Viking Cosmic and a couple other goodies. Maybe the lesson is that it's OK to skip some challenges in order to save your ironite and regroup. (I'm not saying I'm happy about the idea.)
There should probably be some small consideration from the Dev. team for the re-introduction of the 10-second timer and the disconnect issues. Due to disconnects, the most precious resource we're likely to lose is Keys. Due to the timer, we lose speed... maybe as much as like 20% depending on what Frontier we're doing. So, lower each challenge goal by 10-20% (timer increase) and throw us some master keys. That would be a nice gesture. It might not ultimately change the reality that some of us will lose our Ed.
