I don't know if this has been suggested already, so here is my suggestion:
how about we get a speed up buff for general that gives them same movement speed as the marshals or even faster across the adventure map. This will be helpful for those long distance maps like VLT as it saves a lot of time transferring a general from one place to another.
It can only be used once per general probably with a time limit as to make it less advantageous if 'advantageous' is a word. For the price I think it should be less than price of rain of arrows.
