Upsets DO happen. You can waste alot of time by progressing with "wrong" tactic or running into surprise mechanic nbthe hidden phase that ends up forcing you to change your comp. Also people get sick and get into accidents all the time, serenity for example had a firm lead at NH before Russians stole WF from them. While it is unlikely any fresh 10/11 guild still takes it, Limit stealing WF as a first NA guild since HoF is more than possible.
