Stalkers where under played and did need a boost, they where just roaming the fields doing shitty damage and running away when the weapons weren't release yet and Champ, SinX and Clown didn't needed a boost, but the weapons where put out for the class just to have something, said by Veracity himself. There is another suggestion on clown weapons that was rejected.
This is a quote from Miracle from another clown weapon suggestion:
I whole-heartedly disagree with this suggestion. Clowns are fine offensively as it is. Tarot debilitates players by breaking their equipment, casting coma on the enemy, dispelling their buffs, and cutting the enemies attack by 10% or up to 50%. This is off-set by their mediocre, but still decent damage. They don't need to be dealing more damage, and we should balance out the classes by helping those that need help, not by nerfing the classes that are fine the way they are, and certainly not by making them more powerful.
I do agree that Clowns might need a little more HP, but that can be easily done by modifying Tao Gunka's effect.
