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!

I actually wish I had infused my PvP gear. I had a full set of year two new monarchy armor with great perks, but I dismantled it when I got raid armor. Now that IB and Trials are here, I wish I had infused my raid armor into my New Monarchy armor. The raid is so easy, even without any perks. It would've been much smarter to keep my PvP build and infused it up to 310. Oh well. Maybe my Trials Gear will have awesome perks and i can infuse that stuff instead.
