Wtp is so bad about Rage?

Because they have extremely cheap 12 att pots that make rage quite useless.

Those potions are not cheap. I heard in another thread that you're a major FMer; to you the cost of Warrior Elixirs is nothing, but to others can be an issue. Some people are extremely short on mesos, to the point where they cannot afford to scroll decent equipment and are lucky to have enough pots for the next day's training. To such a person having a free 10 att boost over a 12 att boost that costs 500k per 100 potions may be a good alternative. If it's the difference between regularly training and not regularly training, Rage is good.
