Blm also has freeze and blizzard 2 that have no use at all. You can argue blizzard 2 as a pvp skill (so why isn't it pvp). But freeze has no use at all. At least your skill has situational uses and isn't a quested job skill. Lethargy heavy effect is pathetic. I used for T5 progress but haven't touched it since the heavy is so weak you barely notice it.
