So many great comments in here about Spire...I have glanced at Spire now & then. I try to minimize my diamond use in there when possible, so, I have backed out of an encounter more than a few times, til it is a bit more in my favor. I used to be able to blast to the top every Sunday. (For some, Sunday is there funday...for me? It's guess my life away & it is FUN!)...
Now that I have advanced enough in my city, sometimes I have 8 goods to choose from @.@ ...Strategy at this point is dwarfed by 'shear luck'...
My point? If you wish to continue to cater/neg it, be warned. I have paid it forward. It is a REAL challenge now for me, to make it to the top now.
Needless to say, I am trying to learn how to fight manually, because next to building my city, the Spire trumps rank & tourny & everything else for me. The stuff I can get in there is unmatched anywhere else in game, to my knowledge. (And when I am focus-fired on the Spire, sometimes it takes me a hot minute to reply to my FS, if somebody said something to me)...
GL & have fun!
