I don't think everyone should have all stats 99, but could have some restrictions like 'You can only use F2P armour (rune set, green d'hide set for ranged)', 'No curses', 'No Ancients or Lunar', etc.
I agree.

Players and Staff should organize pk events, like FC wars in RuneScape in 2005-2010. It could be helpful to players who wants comp cape and could be a fun activity to others.
