Personally I think having large numbers needed and large swings on what drops just creates frustration - I had to drop 100g and all my gems to get Orph and the left overs went on a boots and a couple of shields

The 1st event was much smoother lower numbers, and just flat drop % sure still RNG can screw you but it's less likely to over the long run, nowhere ner as bad as this could

Also auto complete. Yes please - but not too much more challanging not everyone has god teams, heck I'm still mostly 65 - 75 ish on my levels partially as events like this drain stamina and my team can't complete 2-40 (getting close mind)
