There are quite many dinos in this game and some of them may be considered trolls just thanks to leave their moveset, ability or SIA…
They are sometimes a pain on the way you have to deal with them
Which ones do you consider trolls? Your opinion? Do you use any?
From my point of view I would include in the troll list these two:
Edmontoguana: zombie dino, regen and run and never dies.
Purru Taurus and carnotarkus: special damage to Trykos and tanks in general. Can force an early DC swap.
