All those builds are european builds

There are two things that you can't change when you play a character:
1. The choice between chinese or european character
2. When you level up you get points to distribute between strength and intelligence. You can never reroll those points. So before you start you have to decide about your race and your int/str build. There are hybrid builds but if you are new in the game I would suggest not to try those builds out before you have a better knowledge of the game.
All the rest can be removed and changed and rerolled even if it asks grinding mobs and gold.
When you start a euro character you receive 2 mastery points per level. It means that you are able to level up 2 masteries, not wizzard + cleric + warlock + warrior + rogue + bard, if you want a nice build to level up it's better to take just 1, maximum 2 masteries. The more skills you take the more SP you need and this game isn't a SP donator. So here too, stick to a minimum of skills if you want to level up at a decent rate.
