*sigh* -Both are under Activision so its essentially sharing at this point. The Specialist abilities may be extremely similar, but are in now way as deadly as the supers in Destiny. The time to kill is so high that it is extremely easy to shut down people using Annihilator/Tempest/Sparrow/etc, and the hit boxes are so much smaller so firing off one of these does not net you a kill every time. -Game mechanics are "stolen" for EVERY game, including wall running. Titanfall did not invent this mechanic and was certainly not the first to use it as a key mechanic.
