Well, I will wait untill some other players leave their opinion on this. As far as I see I have’nt been clever yet on why Silence has been nerfed in the currently meta we had from 1.0.7-1.0.9.
I think Zelarith gave a good answer. Silence and disease combined with reducing the teams physical attacks would be a massive pain the ass.
Eh? More like the other way around, as silence gave you a free mana drain… methinks it was never supposed to drain mana, but the devs only just got around to repairing it, probably because of introducing disease as @tacet says…
