The specialist abilities can be obtained through time just like supers, I called thee gun a hand canon because that is exactly what it looks like, not your conventional pistol, a hand canon. Killstreaks are nothing like supers, the only similarity is that supers can be obtained through kills and kill streaks as seen in the name are the same. I played the black ops beta, and it was fun, I enjoyed the experience but that doesn't mean that it didn't just take from other FPS that have come out recently. Parkour, titanfall didn't invent it but they used it in a FPS, one that competed with cod too, and so cod decided that if people left cod to go play titanfall that they'd get them back by adding what made it unique to their game (excluding Titans because that would've allowed for a copyright). Destiny, while also published by activision, is going to prevent cod from having as many sales as it could, so they're going to take some parts that made destiny unique and put it into their game. It's incredibly lazy and I can't believe that they'd do such a thing. Cod is dying and in a last resort they're trying to copy other games to make theirs more appealing instead of actually making a high quality and unique game.
