The website is taken down.
Anyway, from your forum post with egiptian settlement and GE.
Forge of Empires raids is a combination of both Fellowship Adventures from Elvenar and Alliance city from Rise of Cultures, search on google to see what I am talking about.
They are using their mechanics from their other games, trying to make something better.
Now it remains to be seen how better will be.
Map is to do the action, the city(settlement) is to put the guild members producing the guild goods needed to unlock more in the Raids, the more activity in producing, the faster You get the goods, and more.
From all the game files I have seen so far about raids, it resemble to those 2 other games mechanics, nothing more.
Raids will involve the participation of the whole guild there, not only 5-20 people and after only slackers, everyone needs to put the bone at work if they want to be higher in ranking and get x rewards.
That is how I see the Guild Raids working, I might be wrong also and have omited something.
Regarding fights, yes, fights are limited after GvG removal, 500-800 GbG, 80GE, 60-79 Hood, 20-30 from PvP arena If You spend medals/diamonds, some from colony map, and what will be from guild Raids, so a total maximum of ~900-1000 fights per day for the top players.
