The Assault Juggernaut is actually pretty powerful as long as you run with your teammates. If your alone, go find a corner or stay in areas where there is less routes to be flanked until your team mates are nearby.
The Loki is actually pretty powerful. Use the free AI juggernaut to help you get kills. Throw your care packages in the open and blow them up if they try to attempt to steal it. If they hide, at least your teammate or you can get the care packages. It's a win win situation.
Satcoms are ok. I prefer UAVs better since satcoms don't last too long and are spammed like crazy.
I do admit that getting kill streaks aren't as fun since anybody can get it. If it was harder to get the kill streaks then it would be more rewarding.
The KEM smokes doesn't bother me at all. In fact, it benefits me since most people don't know how to deal with the smoke. It gives a big advantage to pro players since noobs will not know where to go or become confused.
i get that they were trying to make the streaks so they're not completely dominant, but i don't think that means they have to make them worthless, either
streaks make the game interesting, and with them being so underwhelming, a lot of people just don't get the same joy from getting that "one" game they do extremely well - and so the game has a much larger diminishing return to the fun factor when playing for longer periods of time
I said this many times myself since the release of the game. But IW caters to a loud whining minority that endlessly complain about things that kill them. Nerfing should always be the last resort to balancing a game.
The streaks need to be improved with the return of the care pack. You have to give even the lower skilled players an opportunity to get the fun kill streaks or they won't want to play. The unfortunate thing about the whining to nerf stuff is that it often comes from the higher K/D players. So what if a crappy player gets a random chopper gunner or AC130. Learn to deal with it.
