Owner may can course of a sub carrying a navigator.
I'd like to propose the idea that the navigator should be able to change course to intercept other subs.
Why?
(1) Navigator's able to constantly change course from losing battles weakens the depth of strategy.
(2) The only counter to combat a Navigator is to have a pirate near by.
(3) The Navigator+Martyr combo is "OP" with only one viable counter, the Pirate.
(4) Technically, according to the specialist description, you should be able to change course to intercept a sub anyways.
But wouldn't that make the Navigator like the Pirate?
Yes and no.
Pirate
Sub carrying Pirate can target another sub. When targeting a sub, travels 2x faster than ordinary subs, then travels at 4x normal speed to nearest friendly outpost.
Yes, it would mean that the Navigator could 'target' Subs. But no, it would not make it like the Pirate.
The Pirate is an Ambush unit. Its purpose is to catch other subs off guard with its speed boost, and ideally, steal all their specialists.
The Navigator is a Military unit. Mainly used to out-maneuver enemy movements. And it wouldn't receive the speed boost that Pirate receives.
No matter what happens, sooner or later there will have to be some sort of balance update to address the "OPness" of the Navigator.
And for the record, I hate people who complain about Hacks, cheating, and "[things] being OP." But I have a ton of high-level winning experience in various kinds of strategically demanding games, and if half of the uses I've thought of for the Navigator are possible, it's only a matter of time before they are discovered and needed to be addressed.
(P.S. - I think their may be a Grammatical error in the description of the Pirate? It should say like "Subs carrying a Pirate...", no?)
Edit: Allowing Navigators to target Subs in itself would not balance the issue. It's a stopgap if anything. But after submitting, I had the idea of also giving subs carrying Navigators a speed reduction. I think that could Balance them out quite nicely.
