This is mostly in reference to the well known, broken insanity that is Dracorat’s swap in rampage, but honestly the principle applies to all ‘swap in strike’ abilities. The simple fact of the matter is; they are free damage and more often than not free kills, which can be swapped in to anything with no regard for matchup. If you get the other dinosaur in range, which let’s be real here is not very difficult, that is a free kill and potentially a free win. And that is just antithetical to the idea of a balanced or fun game.
Defensive swap in abilities I can support. They require assessment of the matchup and anticipation of the opponent’s next play. There’s no point swapping in Alankylosaurus on a Thoradalasaur, there’s no point swapping in Quetzorion on a Procerathomimus, there’s no point swapping in Smilocephalus on Erlidominus. But the ones with swap in strike/rampage can swap in on anything thats in range. Matchup doesnt matter, and that to me is the definition of unbalanced. Now I will concede that the x1 damage attacks are obviously less commonly used for instant kills than the Dracorat’s swap in Nuke, but if that didnt exist they would certainly be used for that purpose in its place, so I would have to lump them all together under the same banner of broken mechanics.
Of course Ludia doesnt care about game balance, so it’s not like anything’s going to change. But maybe the players could start trying to create a better environment in the arena and stop abusing something that they know is just going to annoy other players with how broken it is.
