Just out of curiosity is anyone else absolutely bored out of their mind if they see Marines play Necrons?
I know you asked who else does, but I can only tell you that I don't.
If Marines and Necrons go against each other competitively, both players equally skilled and the dice fair, then Necrons will lose. If both sides tailor their lists against each other Necrons would lose even worse. But there are some really skilled Necron players out there (among those that have not given up on the army for now, their percentage is relatively high) who have no problem beating most Marine lists. Especially capture and control is a mission Necrons excel at.
I, for one, keep games Marines versus Necrons interesting by making some adjustments. First off: we banned phase-out. That makes the Necrons' opponent play the mission, instead of just ignoring everything and sweeping warriors. Second thing I do is try different approaches: I played Necrons with 54% of my army being typhoon landspeeders and having only troops otherwise, and very few of them - and then we got seize ground with five objectives. Etc...
So, no doubt: the Necron codex in its current state with fifth edition rules is broken. It's just under-powered. But games do not have to be boring, you can do something about it! The Necron players should optimize their tactics as best as they can, search the internet, try different builds, make use of all the mean exploits they can. Phase-out can be abolished (one of the easiest rule modifications towards a more balanced Necron army, I reckon). And the Marines can try something different too, make it interesting.
