we all talk strategy, but against crappy oppenents does luck increase

I dont think luck matters at all. When playing calling stations, make pot sized bets on the flop and turn when its most likely your ahead. I think from what you describe you going to far with medium strong hands. If the flop comes ace high and you have ace king, it is not good to get your entire stack in over the next 3 streets. You will have no idea if one of the drawers has caught an odd two pair, pick a better spot.

With constant 2/3 pot sized bets on good flops, there will be a lot of variance but I gaurentee time will take care of everything.
