if truth be told in there current state wormholes are more of a hassle than anything else.
for example when i was playing on a gigantic map my flag ship went into the wormhole and ended up on the other side of the galaxy and it took round 30 turns to get back into range of one of my planets and by that time the computer had already gotten to most of the ananomolies in my system leaving me without alot of bounuses that i would have gotten
now if the wormhole had transportated me within range that would have been great but as of right now the wormholes are next to useless flinging survey ships across the map and they can get u in last place if u arent able to use that ship to get bounuses like the computer player is getting and search out for some good planets
