With the advent of tames like the snow owl and mana which can be given high end saddles and bred, we need to buff the older non-saddled dinos to have other counter options and so the meta doesn't stagnate   Making wyverns breedable or a saddle option similar to equus (ride with or without) would mean more effective and varied counters to manas maneuvering   Griffins similarly would be pull out of just being a quick flight tame and become properly effective again
