In addition to the 4 buttons present for a general (attack + combat preview + transfer + retreat) I'd like one extra button, or a check box for teleportation. It could cost 5 gems to check this off, but if done so, the general transfers immediately to the new position instead of having to walk there.
Please note: This function can only be called in an adventure, so it is not transporting generals to an adventure or back, only relocating the generals to the next attack. You cannot use "teleport" if a general is attacking, only if you are relocating other generals or none.
This will not, as I see it, change the dynamics of the adventure, it will not give extra advantages, only ensure that you can set up your generals faster, and move on. This way BB could harvest some gems, and the 5 gems would be fairly cheap so it probably would be used to a larger extend.
This would especially be nice when you have to get reinforcements due to e.g. a bad block. Relocating to the end of a map can be a tedious affair.
