Februs, I think they will be watching job balance. They do currently have the ability to adjust effectiveness in PvP areas.

Remember the classes and jobs each have different damage dealt, physical and magic vulnerability modifiers since 2.4 and they can change ability/trait effects and durations in PvP areas.

If they think Warriors are bursting to hard, they can decrease the damage dealt modifier.

If tanks are too tough, physical/magic vulnerability can be adjusted.
