"Everyone plays at the same level in Guild Wars 2 PvP, where skill and strategy provide players with the winning edge. All players are set to max level and given all the skills and gear they need to meet their opponents on even terms."
So does this mean I dont have to level my character at all since he gets all skills and gear necessary to compete? I can just create a new character and jump right into "end game" pvp?
For sPvP yes. You can begin to PvP as soon as you exit the tutorial/scripted stage, which is 15 minutes at the most. Everyone will be on equal footing and you will have everything unlocked/available to use. You can respec as many times as you want trying to find the perfect build/skill combo/stat distribution for your play style.
For WvW a scaled up level 80 will be far weaker than a true level 80. You need to actually level up to be competitive in WvW.
