That's a bit like saying that "Rheinland BS is uber cause it has so much armor" or "Werewolf is uber just look at the armor, agility and guns" or "Geb is uber cause it has BS shield"... or my favourite:
"Sabre is uber cause it's only VHF with 7 guns"
There are always more sides to a ship than just size. Spazzydragon explains it. I have ran out of steam writing things over and over again, to be met by "it's uber cause it's small" arguments from people that never fight it or fly it. I have high ranking BAF members who were testing it and were ok with how it is now, at some point I also invited some other BAF people to test it personally.
The size was made this way by vanilla developers, just like Bretonian Gunboat size or Rheinland BS size.
