If only Laetin had an EPT or Scyks could get autothrusters, or illicits. Any of those things would have made one or more playable. They can be one shot through an asteroid at range 3 by a tie fighter or Z... And end up costing twice as much just to make that not happen to them.
So can Stealth Soontir Fel, but that doesn't stop anyone from taking him.
I really don't get your beef. EPT would be great to turtle up when you need to (PTL), but it's not like it's a bad deal to not have one. Autothrusters are nice, but not everything can take it. It's not like you should only take ships that can take Autothrusters.
Laetin w/ Stealth Device means he gets 4 green dice. Always go with either a Focus or Evade token. Depending on what's shooting at you, you have a good chance to evade that first hit, especially if it's a TLT. I mean 3 red dice with almost no way of modifying it vs. 4 green dice with either a Focus or Evade? You have to be seriously unlucky to have that fail. Will it happen? Sure, but the odds are pretty bad.
