Is the crystal tracker-type weapon not mentioned because of it's limited range? I mean, it doesn't pierce but it does area damage that is quite handy to deal with groups of mages and multiple ogres as well. I never enjoyed using the disc thrower much as it doesn't shoot straight. So unless you're right into your target you pretty much have to aim sideways all the time... Being a Quake3 pro for so long, I couldn't stand using a weapon that didn't shoot where my crosshair pointed ;p
Anyways, I was expecting the crystal tracker-type weapon to be mentioned here somewhere and am actually wondering why it wasn't.
