I get the frustration behind being finished off with a swap-in, but I personally find it way more game-breaking to be against an overboosted Tyrant (especially in the speed department, when the dino is already a big hitter) that just has the stats to sweep your team from the get-go, and there is no dino you can use to do anything about it.
The most common example used to be an overboosted Thor, but at least if you invested in the speed of a bleeder or distracter you had a change. Or got lucky with Erlindo’s cloak. With the latest buff, an overboosted Procerathomimus looks scarier than ever. And unlike Thor, you can’t bleed or distract her, and she can Nullify your Cloak.
There is still no “Forfeit” option, so you just waste time waiting for the Defeat screen.
If you use the Rat, and were lucky in that particular game to have her in your random 4, you can at least work on doing some damage to the overboosted Tyrant, and use the Rat to finish her off, before she sweeps your entire team.
Again, I understand where you are all coming from, but I would much rather have the option to put a stop to a Monster that outspeeds all my remaining dinos, and can 1-2 shot them, than just wait for the stomping to be over with, so I can search for a new game.
