question about elsword

ok how is everyone doing but to the point. i have a rs if u dont all know and i was wondering i dont know much about that new passives skill i just want to know is it actually worth getting or no? the skill gives a 10% chance of reflecting magic projectiles so thats like the rune ball, fire balls,arrows,guns,or the magic knight fire ball. now is the skill really worth it?

basically what it does is give you a 10% chance to reflect ANY projectile, meaning you nerf half the classes in the game at a 10% chance because those reflected projectiles can hit them right back.
