Anything to do to improve it ?

501 resil is not going to cut it. imo use a bit more PvP gear you need to atleast have 600-650 resil or somewhere near that depending if 2s with healer or not. http://chardev.org/?profile=371808 Is what i'd run I have also seen some other locks 2k+ 2s and 2200 3s ish run with that.

This is the BiS for 70 twinks. The staff has spirit on it, however the haste and int from the staff make up for the loss of stats from spirit. Otherwise, the trinkets you chose are BiS for humans, however this armory contains different trinkets since the player is a gnome. Also, something that is required for a 70 twink is to have a tazzik shocker as two set off at the same time can one shot enemy players in arenas. Also, taking a double PVO two set as a 70 twink is very worth it and still works.

Note: This armory, in my own opinion, is not BiS. A famous 70 twink warlock was named shifflol, however I believe he may have transferred or something as I can no longer find his armory.
