Honestly, I still pvp before 3rd job, and that mastering of guard will really help (not so much in training). 1 extra hit makes all the difference in pvp duels, and not mastering will give you less change of using a skill before you die (considering 1 skill is usually a 1hko it makes a difference)
Besides that, good job =D
