For me it seems that a lot of PvE content can be managed with any class solo. High end PvE stuff requires group anyway, so then you are best off with the profession that you like, not what most people think is “OP”.
When it comes to PvP, it is mostly skill based anyways. Even if there was an “OP” profession, better players and groups will always win. Also professions/classes that are considered “OP” by the community, usually get nerfed hard, which leads them to be underpowered. This leads to even more “QQ NERF XXX OMGPLEX”, which is always hilarious but also sad.
