What I don’t understand is why Dracoceratops can’t be reworked 100% like Sarcorixis was. Sarcorixis’ swap-in was completely removed and the moves were redone. Still useful, but completely different in terms of purpose.
Like others have already said, the main problem with DC is that it constantly swaps in and out AND regenerates HP by 50%. For most dinos, it’s not possible to take it out in one turn, since the most powerful moves are delayed by 1 turn. This allows DC to KO a dino, regenerate, run out and after a while, comes straight back in to do the same. You always take about 50% of the health off, and it simply regenerates because regeneration is a priority move (and again, aside from IR, all instant moves have a delay).
