Seems a little bit unfair for those lower than 67. An event like this should be for all levels, that way everyone wouldn't be left out. Sad to see endgamers making good stuff out of this event while the rest of us still has to farm our way up.
I think thats actually very reasonable - to make events for capped players only.
Nowadays Leveling up is pretty easy since the Dailies give us huge amounts of XP.
If u are below 67 u better grind / do dailies. Farming is for capped guys,
and this my friend is in almost every MMO i know. Its all about the capped Level.
Thats what the Game / Expansion is about (unless u are PvP twinking). So heads up and grind to Lv 71 m8.
