Drafts although fun - are by far the most unpredictable and sometimes awful game mode in FUT.
The matchmaking is completely random, so one draft you might be matched against a WL elite player in the first round and the next draft, against some div 9 8 year old.
Secondly, you will be playing against teams that generally have the best attackers in the game, whereas, quite often, your defence you'll have to use someone you normally would not want to. It makes defending at times a struggle, so you need to make sure your defence isn't pushed up and aggressive as the counter attacks will destroy you
And lastly, people will do anything to win, so be prepared for horrible gameplay and plenty of dab celebrations
If you enjoy drafts, I suggest you play them at weekends, when all the try hards and good players are playing WL
