Okay! Let me explain this slowly to everyone because people are thinking it's something else when it's not.
*Clears throat*
A mock character is a tester character. A character that you build differently from most guides in either skill or attributes only to fulfill your curiosity or needs in the game. A mock character to others is seen as a "Mockery", and it's not a main character. Furthermore, people are going to tell you, "You build the character wrong!", "noob!", or everything above to bring you down, but it doesn't matter. It's just around to fulfill your needs, not no one elses. Mockery is more worked up than a storage character (character that always stay as a newbie just to carry items), and can be used when you are bored of trainning your "perfect everyone knows how to build from guides" character.
For example, warriors are very easy to make mockerys to me because I use to make warrior classes a lot long ago, and I'm familiar with most skills to build and not to build. Let's say I had warrior 1 and warrior 2.
Warrior 1: I follow the attribute and skill builds suggested by most guides through comparrision.
Warrior 2: I followed the attributes, But instead of putting points in to attacking skills, I put skills in only one of the attacking skills I feel I need and put the rest in another desired skill most people would not do.
Warrior 1 is your main character and Warrior 2 is a Mockery.
Plus, Mockery is a legit character, and it's just one of those things to get out of the box of what people normally do. They can be deleted if purpose is fulfilled. I usually can get a mockery pass job 1 and job 2.
