There's no real list, but I think it's just Dilos, raptors, and terror birds (I think normal ones, not alphas), and wolves that have the pack boost. Dilos are the odd one out for being able to do torpor damage, but it's probably to give someone access to being able to KO dinos easily.

Some stats and numbers have gone up or down for some dinos as well. Baryonyx cannot be carried by argies in this mod as well, so there's probably more dinos with increased weight.

As for Trikes, as of TLC, they are now super slow, but they can ramp up to charge fast. That had nothing to do with EC (mostly). There's also an annoying bug that causes dinos to only walk instead of running, but I've found that KOing that dino helps.
