in that case - i think the others might need to learn how to fight it better...
the lib BC was balanced and balanced and balanced just like every other capital warship during the one year closed beta phase against its most likely enemies as well as other ships of a similar class.
the lib BC is good - but its not godly. - it has its weaknesses like every other ship of its class.
its a bit like the BHG BC. - when you re allowing it to face you all the time, it WILL blow you up - until you learn about its weaknesses... which will not suddenly make it easy to fight it - but gives you an advantage - until the BHG BC learns to fight your tactic again.
that is what "skill" in cap-fights means... knowing your ship and the enemy and its weapons well. - the lib BC is a good example of a defensive and all-round battlecruiser ( similar to the IMG BC ) - it is not very large but has weaknesses, too... and these weaknesses can be exploited by those factions that fight it very well ( rogues: barghest / rheinland: 2 different bombers )
