Even the fact that I'm building up the boost for defending army on all my worlds (4, with beta included, I've no diamond farms build, but I could do it if I wish LOL ), playing GE 5 strongly feels like buying with my very last money a purse !
Just to say that the rewards are nice (Temple and Serpent items are ok), but it will take way too long frangment-wise !
I've listen to the Inno video about GE 5 : I strongly believe Inno is sure planning to bring MORE features later on wherein the players need their defending boost ! So that's why I go for it anyway, which will indeed being a very very long marathon to get it working so GE 5 is not impossible anymore to do the battles !
Now (pure) fighters or players that do not love negotiations (maybe some players hate it?!) ... are disadvantaged till they are able to fight !
