I used to have flamberge, it was a good sword. Although its slow, it is great in little groups, you just have to hold your swing and when enemy is vunerable and no teamates in your swing radius, you swing and take a whole lot of damage from him, so 1 hit with a stick can easily kill him. Also, when you have flamberge I recomend taking a longsword, german greatsword, or the best a barmace with you. I say take a barmace with you because with all the str you put in the requirment for flamberge, will definatly pay off when using the bar mace in 1 on 1. Also, take a shields, with those 2 handers your a sitting duck for archers.
