I dont think we need to have more than one combo because if u have the ability to play a turret like smokey well ,then you will not have much of a problem in any map .for example,u can use smokey in maps like sandbox as well as madness or silence .so i guess having only one combo will do,i use only hunter smoky and have m0.10at this rank.however i find your post extremely helpful and informative.i am also happy with joining the forum.thanks tanki :) :).
