Wormhole defence.

[Randallw]

Can someone explain exactly what happens if you guard your end of a wormhole. I was going by the assumption that I would have an advantage if I guarded my end of a wormhole. I believed that I would be sitting around it and get first shot. In a case I just experienced it made little difference, the enemy came through and I was sitting at the maps edge and had to move to engage not getting any specific advantage shooting first.
