Alliance 5 attack limit
This may Be happening on your server, or it may not be. But this is a very common thing on mine and I don't like it so much. Basically what it is is that when an alliance occupies a mine they have a sub alliance attack them 24/7 to prevent any other alliances from attacking them. That's pretty unfair because they can hold a level 5 mine for quite a while without worry of losing it, and when deterioration would kick in theyd let the sub alliance win, then they'd take over the mine again and continue. So my suggestion is this: make a 5 attack limit per alliance, like there is when attacking a player. This way an alliance couldn't have a sub alliance constantly protecting them. They'd either need hundreds of sub alliances or give up on it. Id say the later is more likely. I'd love to see this implemented in the near future! Thanks for reading!
