Can you please adjust the arena chests and lab shuffles to give us useful (or soon to be useful) materials that are only a few levels ahead of where we are in heroic?

Right now I have fought my way through the IH relic boss in heroic (and I believe at level 78 I am pushing the limit of what I can possibly accomplish in heroic) , but all my arena and lab shuffle mats are for justice gear. I haven't even beat a single LB heroic yet, so I already have all those mats taking up space in my inv. I've been having to sell some of my justice mats when I have lab tokens and blue medals taking up a lot of room.

Even if the arena chest mats were for LB gear, although I wouldn't be able to use them immediately, I could at least look forward to using them after beating a couple more bosses. That would be good incentive. Justice mats however do nothing but take up space and make the arena chests and lab shuffle a buzzkill.

Thank you for your consideration.
