The Heavy Flack has both shot drop, slow projectile movement, and a decently long reload time. It is considerably harder to score hits at range with it than the Manticore, and due to its small clip it is harder to bracket your target than with the lumberjack. An experienced gunner will be able to hit consistently with this weapon, but in the hands of a new player the only way to be remotely effective is to go point blank, which is now no longer an option. Also a galleon has the least control over engagement range, since it can not back peddle and keep its guns pointed on target. The flack may still be useful on sniper configured spires and goldfish but the days of double flak galleon terrorizing the skies are over (at least until the next patch).
