Once upon a time I had a Legendary Warzone Boost (AI Kills). As I started a warzone game, I put it on immediately. Once I noticed I was joining a match in progress, I switched my Warzone boost to a “rare” boost as I didn’t want to risk joining a game that was almost over and losing my Legendary Boost because I couldn’t get enough AI kills fast enough. When I switched, I had maybe 20 seconds left before the map loaded. Once out of the game, I checked my boosts and saw two things: I didn’t receive any type of boost from the rare card I used AND my legendary card was used and wasted. This makes no sense as I joined a match in progress AND switched my req boost do just a rare boost to avoid losing my legendary boost. I’m disappointed that I would lose such a great boost without even using it - this needs a fix 343. Thanks.
