Re: Troll Warlord best item??
Phase + PMS + HoTD + Aquila is enough to solo rosh. I like to get a yasha also for the MS, but this could be replace with a lothar if you like.
Following items should be BKB, MKB, Buriza/Hex
You really don't need blfy if you are only fighting against melee carries because axes give 60% miss and you already have insane attack speed.
Final item build: BoT, BKB, MKB, Satanic, Lothar/SnY, Hex/Buriza/Bfly
You might want to sell SnY late late game because it is only 31 damage and 31 attack speed, an ageis or hex or buriza might be a better use of the item slot.
