First, some facts about the T-rex.
While the arms were pretty much useless to the beast, they weren't as weak as you would think. They each could lift about 400lbs. Nothing compared to what it's legs could probably do, but that's not bad.
As for what they were used for? Well, so far scientists think if they were used for anything, it was sex.
Basically, they think the T-rex would use it's hands to "tickle" it's mate by gently scraping their scales.
Also, one other little know fact about the T-rex is that they were all killed by the Kaiju. ;D
There's a couple more theories about how the arms were used. Could have also been for holding females in place, holding prey, leveraging itself up after a fall.Could all be true, not like we use our arms for just one thing. Also, fun fact, they recently found a really good skeleton, now named Wyrex, with a vestigial third finger(on us it would be our middle finger).
Personally, I think the movie should have gone with the Permian extinction(90% of all life, terrestrial and marine, dead), but everyone knows the dinosaurs, so I'll let them have it.
I think one thing Warcraft has going for it is a decent introductory bit of lore and gameplay has already been turned into pretty decent books that connect pretty well with one another. Doesn't seem like it would be too tough to introduce the world with Tides of Darkness and flow from there to sequels and prequels.
