I would suggest you to train 1st the attacking attributes till 60-80% despite be grey and win the 50% of the XP these will increase the AvQ fast as are low attibutes that will rise fast, and this matters.

Errrr... Im actually avoiding anything tat will increase the grey skill...
I wish the GK trick still worked...
