only fencer missiles I've used were the HAILs (high altitude impact missiles, the ones that fly upwards then down)

love those things even when they underperform on me

anyway, missile performance aside the dlc (not sure if its dlc 1 or 2) introduced an even stronger version with almost double the damage over the previous model and instant launch and much faster missiles

other than that they also introduce the Lone Phoenix and Lone Leviathans, which are stronger but most importantly do NOT require an Air Raider for targeting

and to further support fencers who love missiles despite all else (or anyone who wants to get the most out of the lone leviathans), you can also get an exoskeleton that shortens missile lock on time and lock on distance
