It feel like drones have taken Request Gunships' and Limpet Guns' entire niches in EDF 6

With the doubling of the reload time for request gunships and how effective drones are in general I feel like there's no reason to use gunships. On top of that drones are just more efficient than limpet guns in the situations that limpet guns previously thrived in (primarily underground). Am I missing something or what?
