I think devs totally killed Area 4.
Comparing to other areas there is not even a single useful epic which can be evolved into fast legend/unique.
Area 1 - Concavenator (no hybrid)
Area 2 - Secodontosaurus (no hybrid)
Area 3 - Brachiosaurus (no hybrid)
Area 4 - Grypho/Koola/Raja/Gorgo (all possible hybrids are weak and slow garbage)
There was at least Ankylo but now replace for crappy Grypho. Area wasted. Think most of the VIP members gonna cancel membership in a case living/working in that area. They should rotate areas each month or fix area 4 asap!
