You'd have to change the whole subclass to bring it on par with the sunbreaker subclass. That would mean no trip mine, less agility (titans may be fast in a straight line but are like a boat when it comes to changing direction), travel time on golden gun, 1 m melee range etc. I'd have to agree that the duration for both gunslinger and blade dancer needs to be prolonged to be on par with HoS and stormtrance.
