I’m pretty sure I’m not alone on this suggestion, but I think we all know how incredibly tedious Wave Events are, especially if they’re Ferocity-scaled. It usually takes upwards of 5+ minutes to even properly finish one of these battles by playing the waiting game defending until each individual creature slowly, but surely attacks then counterattacking back, and I honestly think that’s enough time and effort needed to finish an Event. Having to spend 15+ minutes slowly inching through 3 of these battles is a massive, boring slog that the Weekly Ominous Engagement Boss vs Wave battles already present when it comes to grinding Amber.
I firmly believe that a good QoL change to consider re-implementing is that both the Recurring Aquatic Wave & Cenozoic Stampede Events should return to requiring only a single wave battle as opposed to three to complete these two Events like it used to be. There’s already enough time and effort needed to finish just one of these battles for the rewards these Events currently provide. Speaking of time, not every player that’s capable of completing these Wave Events will be able to do so with only a single day to spare.
