So we found intelligent deathclaws in F2, but do we actually know when they started experimenting on them?
They would never go out and help other humans (except Goris, but this in an exception)
Goris was a leader to these less intelligent deathclaws, he could command them as the deathclaw mother in FT.
Intellingent Deathclaws had no reason to be in Fallout Tactics, (...) before the Enclave starts their experiments with Deathclaws.
FT deathclaws aren't the same as these from F2, the action happens in a totally different region and there is another subspecie. Read my quotes. And they didn't have more than 4 intelligence.
