keep the masteries lvl 6-7 lvls below ur lvl, then you could lvl up quite fast(with all the quest) and gain SP quite fast.
For me, I am lvl 19 70% now, I have done all the quest before lvl 19, I got 3k plus SP now, my masteries lvl is 12, I am focusing on bow which I like quite much.
The key point is, you can only take other ppl's guide as a reference not a rule, play the way you can enjoy most, that is the meaning of playing a game, not a robot simply follows other ppl's order.
have fun with SRO
