It may not be the most efficient way to play the game, but if it's fun for you then definitely go for it.
From my view, the most efficient way to play would probably be to rush to lvl 20 while getting blue/purple armour, runes, and hunting buffs/reps. Then doing the plateau weekends for valour and hunting for gold to complete the non-hunting beneficial reps.
However, that's a pretty easy way to get burnt out as well.
