Same query here...I do random readings and enjoy whatever I've read so far (Last Stand of the Wreckers, all the Spotlight, some of the UK collections, some of original Marvel) but they are all bits and pieces everywhere not necessarily linked (and sometimes even conflict) with each other.
I'm considering following the ongoing issues now but wondering if there's any series preceding this that need to be picked up as background reference? (e.g Armada or others, what's their connection with the ongoing?)
