Im really enjoying this game, but for some reason I find it kinda strange how we aren't allowed to attack friends. The reason why is that me and my friends want to compare stats and strengths by battling and have fun. I totally can see why we can't attack legion, for reasons that are obvious. But I think that some interaction between friends is legal, especially if they are on different legions, particularly warring ones.

i actually agree i saw my bro guarding a planet and i thought itd be funny to disable him

It was that way , but it had to be changed to stop kill farming with alts.
Now that there are badges it would be even worse.

You can attack friends. You just have to find them first

unfortunately, you cant attack friends. you can target anyone on your friends list through the legion tab, and there is no attack button. these players also do not show up on the battle tab, nor can you take planets from them. i can see why it was prevented through the legion tab access, but it would be nice to disable them if you find them or are alerted to them. it would also be nice to take planets from them. while i would not disable or take planets from anyone on my friends list out of spite, i would gladly duel them if they asked, and would gladly swap planets for green badges. it would just be nice to have a few more combat options between friends.

you can already take planets from friends... (but you're correct in that you cannot attack the friends themselves, so if they're guarding... oh well)

as for swapping planets for badges..... that's a slow process... there's a 7-day timer on green badges from the same person

if they guard a planet u can in fact kill them,

Just don't click on the use artifacts buttons or you will have to retarget them from the planet.

you can also kill them if you find them in BT
