Not gonna argue the point about Stegs; I think giving them Superiority Strike when they already had Thagomizer is overkill.
However, the change has proven that in the face of a few buffs to the rest of the lineup Raptors didn’t need a whole lot of rebalancing to maintain the spot they were meant for: glass cannons. In that regard, I disagree completely with a health buff. I’m no longer sold on the notion of giving them an extra cooldown on Pounce because as the meta has changed so too have many of the tactics; adding an extra turn of cooldown will force nearly anyone who chooses to use them to swap them out now (whereas currently some people might keep them in and sacrifice them for the extra damage to an opponent, and removing the ability for a second Pounce one turn sooner all but forces it to be a switch-out dino).
What I would like to see is a new Hybrid in the next major change of hadrosaurs and support creatures. Currently we only really have predators, tanks, and predatanks. Why not mix Edmontosaurus with Tenontosaurus and get an extraordinarily potent and mobile super-kangaroo? Or an Ornithomimus mixed with an Iguanadon to give an evasive, healthier, immune stunner?
It is my personal opinion that no dinosaur should be moved to obsolesence. I’m happy to keep raptors entirely relevant - just not frustratingly plentiful.
