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!

Lol, I ran the raid first try without jack shit for armor. Second week I had one piece of raid gear without perks unlocked. If you think raid gear is needed to do the raid, you sir are terrible at this game.
