For me a pot is second, closely followed by firestarting implements. My favorite pots are the ones that will nest around a large nalgene bottle (e.g., Snowpeak). You can have a complete kit inside the bottle in the pot -- very convenient. In fact, I only use packs or bags (like Maxpedition versipack) that will hold a small pot with the nalgne nested in it, even if I'm only dayhiking.
