Another thing to remember is that it does only apply to the instruction skill so it is very limited in effect.
Firstly how many runners actually have the instruction skill, and for those that do how many have it a rating greater than maybe 1 or 2?
Secondly you have to have the skill you are trying to teach at a rating of at least 4 and can only teach up to the rating you have in instruction. Maybe your Face can help the rest of the team learn some low level social skills but beyond that there's probably not much that will ever happen with this skill as it's just too niche and specialised for most builds.
