Arenas, the only place for PvP!
I believe that arenas are one thing that SK needs in order to become a real game.
Arenas should have a service desk were you can learn about the arenas rules and how to fight
there should also be a desk were you can register to fight then the people at the desk take your armor and all that level, aka stars, and match you with someone of equal or about equal level.
there should also be an area were people can go to watch the fights
another thing would be team fights were 2 teams fight each other
one last thing would be guild wars if this is made this is were the guild wars should be held
sincerely,

we dont even know what pvp in sk will entail
