Okay for some reason I seem to fail planet invasions alot. Even when I have 3 times more attack and Defense than the planet aswell as using cartriges. Now looking at all the other timers in the game I notice that if you succeed in hacking/raiding you have a 15 minute timer but if you fail you have a 5 minute timer (1/3 of the success) Why not do something like this for invasion? If you Fail you should only have to wait 8 hours before the next invasion.

Because an engineered virus lasts 24 hours. If the owner of said planet doesn't log on to use a cloning pod, you can just try again for 15 energy. With a hack and a raid, it's essentially the same chances every time unless someone were to use a arti/trap, or install more cloaking/scan.

+0.5, i do feel that 24hours is too long a cooldown for invasion, but 8 hours would be way too little, consider that u might be away sleepign for 9 hours or away workin and be offline for 10hours, someone could have 2 shots at ur planet without u being able to do anythign about it, perhaps a failed invade cd going to 12hours might be more appropriate without warping game balance.

I believe that the 24 hour timer is good. All i am suggesting is that if you fail the invasion you should only have 8 hour timer. like i said Raiding and hacking have a timer 1/3rd of the normal timer if you fail.

I'd like it to be a 20hour timer like the daily reward. I don't mind the fail timer being the same though.

I would like it to stay 24 hours to give the current owner time to react. However i think that timer should only apply to the planet you tried to invade and their shouldnt be a timer if you wanted to try a different planet. Like how you can colonize as many unoccupied planets in a row as u would like.

OKAY NOW I AM TOTALY F'ed OFF. Invasion was a failure.
Planetary defenses were strong enough to ward off your advance
You had a 90% chance of success.

HMMM. 2500 attack and 2000 defense against 0 attack and 0 defense and i still fail. thats the 5th time in a row.

Well its no different with the PVP timers. You might be offline when someone attacks you. And you might have a fair bit of research points, artifact points and Minerals. Lets just say you went to sleep for 8 hours a person could easily Raid/hack you up to 36 times in that amount of time (depending on how many actions you had completed before you went to sleep).
