I assume like many people playing this game, we want to create the most powerful build we can which suits our play style. Meta/OP builds are always going to be the end result of this process. People are always looking for some advantage. Some smart guy always figures out, despite the best efforts of the devs, to create combinations which results in something better and more powerful than other builds. Some weapons, gear and play styles are just better than others. People are going to gravitate towards them.
I think that they need to balance the game but like some other games they could allow players to be more OP in the regular PvE where it doesn’t affect anyone else and make sure no one has a clear advantage in PvP. Some other games have managed to successfully to create this balance between the PvE and PvP.
