Though I have the Star Trek (and now on its way LotR) RPG - i have actually yet to play it - one thing which struck me though was the reaction scores - they all seem to be quite low (even for the 'established' characters) and some are used as opposing scores against skills - has this been a problem in your games? do you often use reaction attributes? It just seems that it is something overlooked compared to beefing up your skills...
