The traits that will seem odd to alot of players are hemophilia(to some extend) and lingering curse(what are you smoking moa?) but heres the reasoning for those:

basicaly your job as necro is to apply pressure in fights. Path of corruption can be realy clutch, yes, but it is not particulary reliable, puts you into the middle of combat and does not realy add alot of pressure in most cases. Your main pressure tool are your auto attacks on scepter, and this traits maximize this.

I also take greater marks over reapers protection because it is in general a way more reliable trait and having unblockable fear can be a game changer(ye so can a aoe fear, take it if you want to but that's your choice).

Also soul marks over master of terror for realy good lf generation which you will need in longer fights while the extra fear duration can be useful but you will mostly use fear to interrupt key skills or set up a burst which wont need alot of duration anyway.
