Playing the Wing Diver, Ranger, and Air Raider it feels like I just have to farm Reconvence for weapons and then use brute overwhelming force on Hardest and overwhelming force with lvl 50+ weapons and a bit of luck on Inferno.
The fencer is more tricky though, as I don't know how to dash cancel and only know how to chain dash-blastspear combos. The fencer ranged munitions are ass though. Underpowered and require you to be rooted (i.e. suicide on anything higher than Normal) and have insane recoil.
Please don't post EDF 5 or Iron Rain as I don't want to know anything about them until I finish this game.
