Sure the game is broken if all you think about is 1v1, but it has really always been a group pvp game and you can counter almost every class with another class, so sure if all you do is rpk HK's or ask for 1v1's then yes 1 Button "I win", but if you actually play real pvps, with you know 2-3+ pties vs 2-3+ pties, then there is no such thing as 1 Button "I win".
Of course some class balancing is long overdue, but there is no such thing as 1button "I win" in a real pvp.
