Linkshells and free companies are different things. Linkshells are meant for social, FC are supposedly for more content focused our grouping together players with similar goals. I run with a static for coil, and it happens to be a mixture of the above.

I guess my point is, don't limit yourself to just partner with people in a LS or FC if it doesn't suit you. Typically, it's best to run with players of the same skill, and time zone preferences.
