Could you show us where the lore says that the Bakka hates attack craft? This is how the BFB document puts it:
"This incident left for many centuries a suspicion of attack carriers in Tempestus battlefleets, and even today there is a tendency for such fleets to favor big-gun ships. This is particularly true of Battlefleet Bakka where the Big-Gun Lobby had subsequently reigned supreme."
This is NOT "We HATE attack craft, they are the worst things ever!!!! Everytime we have attempted to work with attack craft it has been a laughable failure!!!! Battlefleet Bakka page 1: "This 'Young School' proposed a complete change to Imperial Navy fleets based on attack-craft carriers as such tactics had proved highly effective against pirate squadrons." AND "Therefore, there has been a tendency for Tempestus battlefleets to concentrate on small flotilla and anti-piracy tactics rather than a Grand Fleet strategy." Oh, well ya except then we went ahead and made the biggest turd carrier of them all because of a suddenly perceived weakness"
"The Jovian is viewed with misgivings by many authorities in Battlefleet Bakka, as history and tradition are hard to set aside in the Imperial Navy in general and by the fleetlords of Bakka in particular. With the history of the Garerox Prerogative required reading in the fleet academies, the very idea that the Imperial Navy should need a dedicated attack craft carrier is viewed as anathema. However, the horrors of the First Tyrannic War cast a negative light on Battlefleet Bakka‟s inherent distrust of attack craft, and while their tactics of relying on massed battery and lance fire proved effective, it was only prudent that more attack craft should be made available to support the battlefleet." How is this "so opposed to what one would expect from Bakka?" Do you have evidence of that from official sources?
