Spamming Steel Cyclone requires a lot more effort than you think, OP.
There's the TP requirement, it's hard to get TP!
Then there's this thing called a COOLDOWN and it doesn't allow you to use Steel Cyclone often enough.

Have you ANY idea how difficult using Steel Cyclone is? You should level a melee class before you cry about nerfing it.
You have to know WHEN to use Steel Cyclone and when NOT to, it's a thing that only the elite players have. It's gained by playing the job WELL. Like DUH!
