[Resto] 4-piece T15

Hi guys

So, my question is whether people think it would be worth dropping the 4 set bonus (2x502 T15 and 2x522 T15) to switch out the 502 pieces for 522 ones that I have?

Would the 522 gear be better than the 4 set bonus, until I finally get the T15 missing pieces I want?

Many thanks.
