I'm planning on doing a 3 games of combat training, then bootcamp and then pubs.
Hopefully I am not on the bad side of lag comp like I was on MW3..... >.<
It depends on how the thumbsticks on the Wii U pad or the Pro Pad work. If they're similar to the PS3 controller then at the risk of boasting I can say that I will go for higher streaks no problem. However, I'm playing on PC right now with a 360 controller and am doing pretty terrible. I can't believe the amount of difference between the two controllers frankly. So right now I rock UAV, Care Package and Hunter Killer. I always enjoy Care Package early on in a CoD game's life because it lets me discover all the Scorestreaks/Killstreaks before unlocking them and adds an element of surprise and randomness. Hunter Killer is great for protecting objectives. Toss it over a wall and it does the rest.
This xbox controller is killing me - so I feel your pain
I'm running UAV, Lighning Strike and Dragonfire (default killstreaks)
What's interesting is that you don't always unlock high scorestreaks at later levels. I'm level 10 and I can use the VTOL Warship (chopper gunner) but I have to wait till level 30 to get Counter UAV. Although the 2 most powerful killstreaks are the last ones to be unlocked (dogs and Hunter Killer swarm)
