I haven't read all the posts so i don't know if anyone has said something about it or not. Thanks to matchmaking, its normal for me to encounter 'Warrant Officers' (all) in a match. Earlier it was Sergeants only ( I am not sure about it but the type of equipment they had, they were surely in Sergeants group) It was easy for me to complete 'Finish in top 3 in the winning team', now thanks to Warrant Officers who have M1 turrets ( which my Mammoth M1 - which i got in a sale - is unable to survive in front of those guns) I would rather change that mission i like the concept of matchmaking but if this ranks problem could be resolved this game would still be in my favorites.
