They deny that because they have a high leveled legendary dino with a unique over leveled touch on there team. To help steal those easy wins.
They’re not that easy to kill. Let’s say your dinos are around lvl 19-23 but players come in with lvl 25-26 DC down in marshes I seen it. You will need RNG to take effect with a critical Thor lvl 22 hit at least if its even in your deck. And down in marshes not a lot of players have the means to take it down. So they swap regen stun until its over. Then if you kill it after it takes 2 dinos out or severely damages the second dino, its extremely hard to get ahead when they can also pull out a Thor or indor. That’s almost an auto loss. I still try but I can see why some just say screw it. I normally just call the players something I can’t say on here xD
On the other hand a trend… A lot of DC users are quitting when your dino crit kills them then there whole gameplan is out the window.
