Golems are the answer to "what should I spend my money on if I already have a huge fleet?"
The answer to that would be mercenaries imo. ^^
Or did the way mercs and their ship-caps are handled change recently?
That is one answer, yes. But golems are another.
Excuse me? I wasn't talking about broken golems. I was talking about golems that have been in a fight and need repairing.
Ah, okay.
Golems are the answer to "what should I spend my money on if I already have a huge fleet?"
That's what mercenary ships are for! What is the point of introducing another unit to fill this role when mercenary ships are probably the most under used units in the entire game?
In fact, what you are advocating is specifically what I am trying to avoid: picking up golems "as a matter of course" and having them be just this awesome thing that doubles your effective power (or better) for no particular drawback.
If you are specifically trying to avoid this then what are they doing in the game? What is the point of a unit that makes life a misery for "coolness"? I didn't say that they should have no drawbacks by the way, they definitely should, but they should be something manageable.
In my opinion it should behave something like a fortress. It should have weaknesses and strengths. And for a massive ships it should bloody well have better strengths than weaknesses.
A lot of players who are more advanced use mercenaries quite a bit. But, having simply 3 ships that are mercenaries is less interesting (and, in aggregate, less powerful) than having huge numbers of ships. Also: for the artillery golem in particular, actually the numbers you are saying sound right about perfect to me in terms of time to repair. It's meant to be a one-use sort of golem, unless you bring it home and spend hours repairing it. It's waaaay overpowered to be used in any other way.
Golems aren't only about the "cool" factor, but they are something that are meant to be used only in more extreme circumstances. People can't seem to stand any ongoing AIP cost, so the time/resource cost for them either has to be extremely large, or they have to not be repairable at all, or a similar concession has to be come up with. Costing a lot is not a particular "weakness" to a ship of this sort -- it's just a prerequisite that you be pretty wealthy in terms of resources in order to be able to use it twice, and that you can only use a given golem once or twice every 3-4 hours or more if it's getting busted up a lot. Having a golem in every battle would be disastrous, but that doesn't mean that they serve no function as they stand.
Fortresses are different in that they cannot leave the planet they are on. Thus, they cannot be used to offensively wipe out the AI in repeated uses.
