I'm mid-50s rank and yet to attempt a planet takeover (haven't needed to, thus far: unoccupied planets have been sufficient). There are some occupied planets I've picked up that I like the look of, so I'm thinking to try a planet capture next time I can get a planet.
What I'm wondering is: Is there any generally-accepted etiquette to planetary takeovers? It's fairly obvious to me that inactive players' planets are fair game, and that if an active player is making good use of his planet it would be rude of me to steal it unprovoked (I wouldn't want someone to do that to me). The ones I'm questioning are held by players twice my size, but they don't appear to be making use of the planets.
For example, there's a rank 100+ player with an Average, Very Rich planet. He has 17 structures installed, all the lowest level, and only half producing resources. The rest are entry-level attack, defense, population. Possibly inactive, but I can't remember exactly what rank the owner was when I scanned the planet three weeks ago.
Or, there's a Large, Very Rich planet occupied by a different rank 100+. Probably only semi-active (he's gained one rank in three weeks), but he is the leader of a small legion. These are the only structures on it:
- Surface Bunkers Defense: 25
- Surface Bunkers Defense: 25
- Orbital Minefield Attack: 25
- Orbital Minefield Attack: 25
- Research Station Research: 1
- Surface Scanner Artifact: 1
I could easily take either of these planets, and I think I would be justified in doing so (the owners are not really using them; why should they be allowed to keep them?). But would such a takeover be reasonable in the eyes of an outside observer? Could it be done without making me a target to the owner's legion?
Thanks for opinions & advice.
