IB gear = fake 310s which means you are booted from my fireteam.
IB gear drops at 280 so you will have to infuse your way to 310 which isn't worth it. Plus using IB gear in the raid is worthless anyways.
Edit: only true year one vets know what I am saying. See all the salt posted below!
Edit 2: updated satire tag. Salt game is strong!

Honestly the IB gear for the most part looks 1000x better then raid gear
