They're fine in crucible but fusions are not as useful as the other special weapon types for any PvE event. I recently tested a 365 Praetorian Foil in a level 28 Prison. It took three shots to kill a red health Cabal Centurion. For comparison, the same enemy dies from one shotgun headshot or two sniper headshots. Now, I don't expect fusions to be as strong as a shotgun but a 50% damage increase for PvE would at least make them worth carrying. [b]Edit:[/b] I'm glad that this thread keeps getting bumped even a month after posting. As the new incoming patch notes display, the devs seem to be oblivious to fusions' lack of purpose in PvE. The more this topic is bumped and liked the more they'll notice our concern. As for the example I cited in the second paragraph above, I'll explain why I chose it in case anyone is wondering. The Foil has the highest impact of any normal fusion, comparable to the old 77 Wizard and the new Aksor's Servant. Foil's solar damage also matched the shield element of a Cabal Centurian, so the first blast did more damage. Attacking a relatively low level enemy also meant it would be easier to kill than a higher level enemy. But even with this ideal set of conditions a top tier fusion rifle takes way too long to get a kill.
