Hey guys!

I'm new to prot tanking, its my alt. After I dinged 90 I got the chest and gloves crafted(ilvl 496). Yesterday in LFR I got the tier chest and shoulders. Is it better to change my crafted chest to the tier chest, so I obtain the 2set bonus? Or should I keep the crafted chest and keep the flat stat upgrades?

Thanks in advance.
