I'm trying to decide which line of catalyzer to go for. The only use of the Biohazard I can think of would be RJP or T3 jellies (no gremlins, they're too fast), but I'm already working on an umbra driver. I've also heard a lot of good things about the Biohazard, though. On the other hand, with the Neutralizer, can it compete with the Valiance? I was thinking about possibly using it as an FSC and general-purpose weapon. Is its blast radius large enough to deal with crowds of slags?
Can anyone with experience with either of the two, or preferably both, give me some guidance?
