The Missing Piece, A well rounded group this ain't... Options

[Paul]

So how do you handle, at your table, a team of player characters that's missing something? For instance it's looking like my upcoming campaign arc will not have a Technomancer or "Hacker" style character, and maybe even no magically active player characters. (Two people are still generating characters, so who knows.) But at any rate how do you handle this at your table? Do you subcontract? A liberal dose of handwavium? Or something else entirely?
