Transporters are amazingly slow
Speed of 500. The Subverter, Overseer, Devastator, Desolator, and Skirantra Carrier have the same speed(the Evacuator is slower and the Marauder can go faster if it wants).
and they build strikecraft incredibly slowly.
Vasari Fighter Squadron: 96 seconds
Vasari Bomber Squadron: 90 seconds
TEC Fighter Squadron: 120 seconds
TEC Bomber Squadron: 125 seconds
Advent Fighter Squadron: 144 seconds
Advent Bomber Squadron: 126 seconds
If the Lasurak Transporter is slow, the Percheron and Aeria are slower.
Good players guard their fleet with flak, which means to attack anything you need to go through the gauntlet.
They either have to spread flak too thin or put a lot more resources into flak(which means less resources into killing their enemy's direct-combat fleet). Flak spread too thin can just be flown through by Vasari/TEC strike craft without too many losses, and can be themselves focussed on by all the Bombers and Light Frigates at once. Flak clumped up too densely can be dodged.
High-HP heavily armored Vasari Bombers are in the best condition against flaks, as innociv said, when compared to other strikecraft because they're individually the hardest to kill, and when one of them does get killed, it can be replaced by the time another one gets killed.
you have a fleet doing nothing (since you can't chase them with transporters).
Who says your fleet must consist ENTIRELY of Transporters?
I've been playing TEC mostly, so when I build Sova carriers, I give them fighters since one of their specials is Strong Fighters.
Heavy Fighters. I think the buff works on Bombers too, but not sure about it.
Actually most of these tests are against Light Frigates and I think a carrier, just like the other cap ships, should be able to defeat an equally priced group of light frigates in combat from the start.
See my Aeria vs. Disciple post in the Strike craft Newbie Doubts thread by Belfrahn. Look at how Light Frigates are a direct head-on counter to Cruiser Carriers, while neither Bombers nor Fighters are much good vs. Light Frigates. Fighters barely even scratch their paint, while Bombers do half damage.
