keep the following
https://wiki.project1999.com/Reaver - For dps role or solo
https://wiki.project1999.com/Infestation - mainhand aggro
https://wiki.project1999.com/Sarnak_Warhammer - secondary aggro
https://wiki.project1999.com/Tserrina%27s_Whip - to snare if needed, although i never had to snare as war
Slowing weapon and life tapping weapons are really meant for soloing. My war was super geared during the 50s and soloing is still slow as fuck. I can count the number of times I had to pull out scimitar of lifestealing or truncheon doom.
I say skip frostbringer, its good aggro and ratio compared to sarnak hammer but it's too common and fugly. Infest + sarnak hammer is suffcient for aggro until you get VP, epic, and ToV weapons (or willsapper if you can stand its fugliness and mainhand piercing animation)
