Xp Boost, collision, and store

First off the cost of items in the store is complete trash, however I understand 343 and Microsoft are gonna make their money(whatever). Like they don’t have enough right? In a game, that I genuinely enjoy the hell out of, where it takes so long to level up, why for the love of God does the double xp boost go off real time!! When I’m waiting In the lobby for 5 to 10 minutes I shouldn’t be losing my double xp. It’s not my fault yalls severs are trash at this point! Only other real complaint I have is the collision in the game if I go to back smack someone and they back up then back smack me one more time im gonna scream! I can’t be the only one with these issues right?
