The move in and out tactic and also the first wave you absorbed without damahe will be obsolete in 1.12 as there was a problem in the code where AI won't taking into account the Player counter measures and was not learning from it. It is possible later you will be lured in before getting stormed by AMM. For the rest it's not that cheesy, it's a tactic snd there is nothing wrong in using it. AI actually does the same sometimes.
