Meth is unmatched not just for flight, but also for the fight part.
I recently had a survivor who took down a fast hulk with less than 3 melee. By “fast” I mean hulk with “Fast Zombies” mod, which doubles all zombie speed.
Granted, it was one of “those” survivors who start with toe talons and find a combat knife on the first day, but still - fast hulk on the second day. No traps, no tactics (the fucker ambushed me and got the first hit, smashing me into a wall), just me, talon, knife and meth.
Meth saves lives.
