This has been our biggest challenge. Its very difficult making a player seem “Powerful” against monsters while keeping them on fair ground against players. In the end we’ve chosen to focus the majority of our Career Balance around RvR FIRST, and PVE second. This means we are always balancing the dynamics of the career (Damage, Defense, Healing) around their RvR roles. From there we go back and balance the monsters and encounters to the players (Not vice versa). This is the opposite of many PvE focused games.
That’s how any game with PVP in it should be. If you are going to half ass it, why bother implementing pvp.
