I have 240 of Ardentismaxima so far because of the championship and because I darted Quetzorion on the anniversary week. But I was working towards mammolania, and I can easily get enough mammoth (I have a level 20 meio and I’m set for elasmo) in 2-3 months I’m thinking. If I only did mammoth for 4 months, worst case scenario I level mammotherium to 20 and I have 15 pops at mammolania and get 150 DNA. If I do Ardentis, I’ll only need to do one pop but mammolania seems to be a bit more useful from my experience with mammotherium and ardontosaurus (poor man’s versions of both). So who to go for? The immune tower, or the OP son of a cow?
