Agreed! Instead of the fateweaver you could get 3 tzeentch heralds on chariots. All the demonic gaze/bolt shots will be useful in blowing open transports and gettings to the guys inside out of the tanks so you can get that tally up.
Honestly the biggest threat to the epidemius build is transports. If your only way to get rid of tanks is assault then against an all mounted army (which there are a lot of) it will be at best turn 3 before you can even start getting the tally up (land 1, assault tank 2, assault guys 3), and you've eaten 2-3 turns of shooting in the mean time. If you survive the tally might get up to a useful number by turn 5, and then the game might end.
Fateweaver can be great, but you need to use those points to get the most anti tank shooting that you can, and I think there are better options in the codex.
On a side note in general I am not a fan of the epidemius list. In order to get the tally up you need to kill troops. Almost all the tally buffs make you better at killing troops. The buffs make you better and something you already built yourself to be good at. It's just too inflexible for me.
