1. Yngens numbers are not correct, because each shield bat and nanobot has a regen capacity of 300.
Example1: VHF with 10000 hull and 70 bots, without armour upgrade.
70 bots x 300 = 21000 capacity. Gives a bit more than double the hull regen.
Example2: VHF with 10000 hull and 70 bots, with armour upgrade 25000 hull.
The whole bot capacity will be lower than to regenerate the hull one time fully.
I'm also convinced, the armour upgrades don't work as they should.
Nevertheless, the fights are quite long and will be, because many players will just evade enemy fire, til their shields are backed up automatically.
