I have a hard time on Terminal,
it seems like a small map, but there's long sniper sightlines EVERYWHERE. Plus the camping spots. The MW3 maps can be boring and are definitely too cluttered/small sometimes, but playing Terminal again made me appreciate some of the things they did with map design in MW3.
The MW3 maps usually have multiple routes to most spots which helps prevent camping, have long sight lines mixed in with CQC sections so you can try to avoid spots where you have a disadvantage bc of your gun choice.
Example: Mission, if you are using a shotgun, you would usually avoid the long sightlines on the side of the map, but you'd thrive in the middlle of the map where a sniper would avoid.
I don't feel I can avoid being picked off in Terminal by a camper or sniper in almost any location, which some might like but I like being able to navigate the map smartly to cater to my style and choice of weapon rather than worrying about random bullets and dark corners.
I also used to camp in the cockpit and on the elevated area beside the escalators.
