fair enough. You could try to explain why.
Infiltrator:most bases have 10-20 shields, so usually the extra 10 would get wasted anyway.
Intelligence officer: probably, the best idea on here but a little too much for a global effect.
Diplomat: Meh, not really needed, one is fine a is plus it makes the general even more exploitable.
Princess: again, not too bad. Interesting with how the queen works. I'd actually support this one.
Thief: the thief is already really good at 15% no need to improve it.
Pirate: 3x speed is really fast and unnecessary, plus it makes it able to catch a helmsman which is cheap.
Tycoon: I love this specialist, but it's not overpowered especially not by 30%.
King:makes him pretty useless, I haven't had problems with kings at 1 to 3 like others had, so I don't think the king needs changed.
Navigator: then it's not a navigator anymore. Unless you mean you can alter its course in the present only which is just really annoying and takes away the great usefulness of the navigator.
MoE: he's not overpowered now so there's no need to weaken him.
Admiral: 2x local speed doesn't make him overpowered.
Tinkerer: he already has a REALLY negative effect. There is no need to make him more useless.
