So a lot of people say they hate them, how they were such a waste of time (True, time could of been spent elsewhere) but I'm now one of the few who loves it and has found a great use for it since the TR items were released.
I now have as much aetherstones as I need (7 million) from salvaging useless items from an inactive I always hit.
Because of so many aetherstones I now have a Lvl 9 ore guardian in every city from crafting Obsidian Ruins.
I now have means to get a Bloody Fury and Iron Skin whenever I need them.
I have enough dragon wings from crafting to hit people a lot farther away with full RP's.
During the summer I normally suicide all my troops so I can relax and not be bothered by the game, because of crafting I don't think I need to now.
I've currently been working on crafting many Horns of Majesty, I have 2 now and the 3rd is in the process of crafting right. That's 9 days already of -50% troop upkeep, and they add up fast.
So I think if a lot of people start using the Fey Tower a lot more a lot of things could become easier, and you can become a lot stronger.
My recent thought, a Horn of Majesty is for a whole 3 days of -50% troop upkeep, 3 days is plenty of time to craft another so if we aren't lucky at getting the troop upkeep bonus from the Throne room this is a much simpler way. So basically everyone who is willing to work can have double might.
