So with my experience in 2.0 thus far I believe that 2 dinos have emerged as pretty difficult to counter:
Ardentismaxima- unless you have a bleeder it’s hard to counter. Plus it can always just swap out, so combining bleeders and pinners won’t really work. It technically can be distracted but let’s be honest… it has 2 rampages and a 30% Crit. Lots of dinos hit it once and then die. It needs more counters in my opinion.
Trykosaurus- I love this toolkit except for resilient counter. A little broken when combined with resilient impact. The double-slowing and anti-dodge aspects makes it pretty hard to avoid a full on dsr from Tryko. I know this is a lot of people’s favorite dino and I see why, I love using him too, but I think his counter attack needs to either go back to just a plain medium counter attack, or maybe not slow, since that’s what resilient impact is for.
