I don't get your point or how it contradicts mine.Hardly.
The worst case scenarios based on the list given are:
• You lose some opinion with a friendly neighbour
• You forcibly give favours and some EC to a rival
• You potentially have an opinion change with a friendly neighbour
• You could lose / have a drastically diminished starbase (just 1)
• You could have an aggressive fleet appear in your territory (that actually requires a response)
• You could have to put up with some ethics shifting
• You could have a planet revolt
But again, these cost influence so this wouldn’t be happening every other game month, but on occasion, like once every decade or two.
EDIT: Would otherwise agree with you if the resource was still EC as you normally have several thousand of these at a time, so it would be spammable.
I was giving a made-up example of an operation too powerful it can not be not too disruptive for players, no matter how high the costs are.
I merely stated that even if you overcompensate with costs, there should be a limit to how powerful operations are.
All that was too illustrate that point and i was not stating that OP or anyone else in this thread was suggesting an operation like that.
