Is it worse than The 4th Horseman's reload?
4th Horseman's slower reload actually makes sense. To compensate for the drastically higher burst DPS, it takes a hit to sustained DPS. Zaouli's (and basically every other KF primary) is barely competing with the other legendaries in its archetype. If it fired faster or had significantly more damage or range, then maybe the slower reload would be acceptable compensation, but it doesn't.
Ah. So how many seconds does it take to reload?
Like 3 to 5 depending on what perks you got on
