Is this happening to anyone else?

I’ve been playing Halo 5 since it came out, I pre-ordered it in fact, the only games I own other than games with gold is H5 & MCC, I’ve racked up a fair amount of hours and there’s hardly a day that goes by that I’m not spending at least 2 hours on the XB1. However I’m still only level 62…

My boosts just never seem to work, I mean, I get them, and I can add them to a pre-game. But without a doubt, EVERY SINGLE TIME I get and use an ultra rare or legendary boost on a match, I’ll play the game till the end of the session, the game will end and I’ll randomly be kicked out of the session. It doesn’t happen until I use those boosts. It really peeves me more because most of the time in Warzone, it’s me carrying the team to victory.
