Everyday, Bloo posts something on FH that reminds me why I love him so much. I don't have tempest, so I donÄt know what else you can forge there, but all of the tempest maps I've seen so far had the beam. I mean, it looks nice, but I think that it will become overused too.
I was lagging down by the Power Source, so I don't think this map is a the lag cure-all. I haven't noticed any lag around the beam, but I haven't tried building there yet.
