I thought WoW was removing talent trees or something.. ?

Besides haven't the dev team said that in future we will get alternative jobs for each class, the community will always find the best way a class/job works so customisation isn't that important unless you want to be some special snowflake of course.

Even in WoW there are specific talents you are required to take if you want to be sufficient at the role, its not uncommon for people to shun players based on the talent builds.
