It seems like there's been some renewed interest in riggers since Rigger 5 was announced recently. I'm all for that, as it's one of my favorite archetypes. My first Shadowrun character ever was a rigger back in 3rd edition. I'm curious to see what kind of advice I could pull together for riggers and players of all experience levels. Largely because I want to be able to play/build/GM them better myself.
So, what are the five things you think every rigger rigger should know (or do)? Can be combat tactics, character generation tips, role playing advice, best practices, best gear, common mistakes, overrated or underrated choices, whatever.
