I miss the old PvP.

[Crit]

Do you even have a clue on what you are talking about?
You are clearly have not played old system.
Under old system, every job has a form of damage reduction and it is quite impossible for any job to one shot other one.
Maybe redefine your idea of "one shot"? If you need more than 3 GCDs to kill someone it is not really one shot

You don't know what baiting and/or trading defensive cds is then to open up burst windows
