Hi there~ This is my first post on the forum.
I'm an avid fan of FV though I'm not that good yet.
This guide is really informative but I have something to share here.
I think the answer on whether to get MoM/Satanic or PT/BoT is very subjective.
Like, if the game drags on until late, perhaps MoM can be swapped for Satanic and PT can be sold for BoT since by that time the IAS by PT can be negligible as compared to the other core items you might have gotten, e.g. Butterfly.
Satanic is no bad choice actually 'cos initially the Helm of D can be used to dominate creeps whose aura can be helpful for you while you MC. Like the centaur's IAS aura and the wolfie's Command Aura.
Well, I still think everything depends on who you're playing with and who are in your team.
PS: BF is not a bad item, but 2 BF is unacceptable to me.
I don't see how an item that gives 60 ias is unacceptable on a dps hero. While the evasion will be useless, you still get quite a bit of armor and damage too, and since it's attribute based it will benefit from a teammate with vlad or your own suggestion of a command aura from a neutral creep.
