Perhaps its your sound system but I got grav round last night and it has a pretty deep base sound on my surround sound system. I will agree that beam looks a little weak but I can also see there is a vortex graphic on the target you hit with it which looks kinda cool in my opinion.

I guess the simple answer would be to send your companions on more underworld trading missions or buy it off the GTN.

Does anyone know if armstech is any good at higher levels? Right now it seems that very few people are using this proffesion. I can't even find mats for sale on the GTN for this profession. Also does anyone know if you can get a critical while crafting orange gear to get an extra slot?
