becasue u r a brigadier grade 2 leveling is going 2 be a lot harder instead of u being a normal brigadier. what u could do 2 take leveling easeier is quiting other game types so you demote to a brigadier grade 1. and once u hit 45 in lone wolves going up 2 50 will take less time if u keep on winning
