Hard raid you get two drops for each checkpoint! But it uses your normal drop on hard! So my recommendation is to get to lvl 29 find peps and run it on hard only from then on you get two chance for any gear including the hard raid gear. The chest are simply one and done for the week no matter on what mode! Edit: if you run it in normal first you will only get one drop on hard if you run it again in the same week so again once your 29 just raid on hard to get the gear you need faster!
