One year old post revived. hmm.

Since your offer no information on what you want to use the champion for I can only speak in generel terms.

I see battlesage as a mediocre support/faction war champion.

I dont expect much from her A1 since she wont use it that often and I suspect it will not give that much damage. So I would focus on speed and surviability. So max her speed and get a good mix of defense/hp.

Vergis I hear is actually pretty good since last update. I suggest looking at Stewgamings guide:
