Even before 1.7 some dinos changes attributes, become better and some worse.
After 1.7 we all know many players have dinos in progress and aswell dinos who now becomes less attractive.
I will show 2 dinos.
And probably you have more example?
Does the meta change to fast?
Have you started to level up dinos to your team, where you now stopped the progress?
Who playes this anymore?
