I believe EVERYONE thinks campaign is (or was) absolutely brilliant. The difference in dinos, having to use different skills, using creatures I may not use normally etc etc and the rewards were amazing. However, like some things in game (looking at you alliance rewards) it seems like a set and forget feature.
Personally I would like to see campaign reset each month with different themes that feature or require different creatures e.g. I don’t recall facing any flyers or using a stegosaur.
However, if a monthly reset was the case I would argue a nerf to the rewards as giving away 100s of unique and legendary DNA is a bit OTT.
