Everything sucks as a secondary after you have an Ice Breaker. But we're talking Pretorian Foil and why no one uses it. It's not that great compared to an Ice Breaker...or most other secondary weapons that are available. Too slow for PvP. Not good enough to use over an Ice Breaker in PvE. That's why no one uses it. When I use my Gjallarhorn in PvE...then Black Hammer or Light of the Abyss take the spot.
