we definately had this in 1.0 before the jobs were implamented and everyone whined "I want more definition." "i dont like all classes being able to do whatever they want" So they gave us jobs cause people didnt support the freedom to be anything you want. And honestly i like that in this game Se controlls what job does what. If xi taught us anything is the the bigger voices get decide how you play. And it was changing all the time too. "Oh im sorry did you start Warrior 5 years ago and liked to tank? Well to bad. [Warrior][No thanks] GO level something else now nab"
If you want to play something with a skill tree there are options for you. Go play them.
I'd rather SE control that for now.
