Breedable dinos i could actually understand.. adult ice wyverns from ragnarok can NEVER BE BRED. fire, lightening and poison wyverns from any map can also NEVER BE BRED. so the point of having anything over a couple of wyverns per person in your tribe is just dumb. there is no reason to have 400+ non crystal isle wyverns just sitting somewhere.
crystal isles wyverns would be the exception to this as you can actually breed those so that is ((basically)) a completely different kind of creature. additionally you dont have to have tons of dinos sitting out. breed it and put it back in a pod, or only breed one strain of something at a time. they cant breed again until the timer is up anyway. or breed more strategically and selectively. it does not matter the number of allowed tames is, honestly if people are going to alt tribe it to get more dinos or some other junk, what makes you think they arent already doing it now?
