Do feral druids always have to rely on survivability?

Feral Druids, as all the cles of WoW rely on skill of the player. Feral druids can use cyclone but everytime it is used, the length that it hold the enemy is shortened rendering it useless soon. All cles of WoW are different and for some people, they can only play a certain cl. The only way to find out which cl you are is by playing them.
