Because that doesn't sound like fun, and I am not running a simulation so I get to focus on what's fun for the players.Why wouldn't you scale these up to the battle riders that carry capital ship killing weapons? Why risk a single life when you can have virtual crew, robots et al operate your warships...
The people can stay on the carriers, tenders and battle directors, ready to jump away if the battle goes against them...
the sad thing is if you apply MgT rules and supplements as written this is how it would be done, and only the Hivers value life enough to do it.
If they tried flying fighters they would very quickly cease having fun with those, too!
