Indeed it is. Me not being able to make an "unbalanced trade" or kill a player without them expecting it, or stake in the duel arena, is wrong. A lot of people made their money by player killing, or staking, or merchanting.
Imagine if you went to college for several years training a certain skill, and you work for a while, and then the government says "Hey, we're taking away your job, go get a new one." You've already spent years in college training a certain skill for a certain job, and now all that means nothing because they took away the job that requires that skill. The only options are to live life with no skills and a dead end job, or go back to college and practice a skill for a job you already earned. It's like they're throwing the player's hard work out the window and telling them non of it matters. All those years you spent in college was a waste of time.
