Versatile Mage: Why Are All My Traits Drawbacks?

Su Chen transmigrates into the world of Full-Time Mage and awakens a Trait System. Except, his traits seem a little off. Why are they all downsides?!! [Language Barrier: You can't understand any language, and nobody can understand you.] [Danger Alert: When you encounter danger and get closer to it, your body will feel intense fear and weakness.] [Burdened Journey: You must carry a load weighing at least half your body weight at all times, or your physical abilities will decline drastically.] […] Drowned in traits with negative effects, Su Chen is completely dumbfounded. But soon, he realizes that things might not be quite as they seem. It's true that he can't express himself in any language, but he has gained the ability to sense minds. He can sense and influence everyone's emotions and thoughts. Isn't Danger Alert just an alarm that turns him into a giant earthquake detector? And as for Burdened Journey, ever heard of Saitama from Full-Time Mage? But when I take off the weights, my body's limiter... unlocks!!!
