We don't think that everything is okay with the game, and you've pointed that out yourself given how many complaints there are regarding balance between classes. However, you haven't even reached the baseline for Warzone appropriate gear which is incredibly cheap, so your entire perspective is off. You can get the full 204 set in a couple days of doing casual warzones.
Honestly this is part of the problem with leveling being so fast. People breeze through the content, don't know how to play their class or bother learning about game systems, and then are shocked when they get exploded when they try PvP.
