You are not providing any information what level his masteries are or anything else.
You will not be farmed if you go 0 gap, exp is 10x but so is sp.
So you will get sp very fast but the same ratio as exp, so farming is necessary,
just like normal sro, only 10x faster, I would recommend that you farm at the lower levels
if you have a friend that can help you level, (it is faster to level alone).
But you can still farm at higher levels.
Up to you.
