Trust me.. If someone wants to get to mid, they will do everything they can to get to mid. Build as high as they want etc, you gotta be smart! :D
Building high is a terrible idea.
They can bridge underneath you without you knowing.
If you have a teammate on the bottom and gets killed you don't have time to go back down.
If you die up top, they'll have that bridge and use it as a camping base & tnt dropping bay.
Let's say IF you reach mid, what then? drop down? potentially die?
survive to just die to a 3v1?
