The main problem imo is that there are no effective counters around; or at least not more than enough vs therapods. During night time anyone can get big level therapods in no-time. Even during the day a couple of therapods appear. Meanwhile there is literally only one effective counter around in my area: the stegosaurus. Ofc. this hybrid easily takes care of raptors once leveled (second picture).
Dinosaurs with beneath skills need to spawn way more frequently as in my area i literally never see them around, ever, unless i see a lucky epic. The kentrosaurus is a perfect example of an effective raptor counter:
So is the stegoceratops but is harder te create because you need a rare:
Last but not least if those are not around one of those will also help but mostly end up being a really close fight (too close sometimes):
There is a variety of slowing impact dinosaurs which of almost none spawn nearby; only lucky drops via the battle arena incubators and even then most of the time i only receive the newly acquired irritator over other much needed rares. The problem is not certain things being overbuffed; its the fact the effective counters are so hard to come by (without having to pay for better incubators,…!!).
Argentinosaurus, apatosaurus, nodopatosaurus, tuojiangosaurus, amargasaurus, … and above examples. Pretty much all the longneck type of dinosaurs and those with slowing impact. All of them are pretty much around level 10 - which is never enough in top 500.
