Before saying that any faction is OP or weak depending on the tournament results try to answer - how skilled the Players were? Would they win if they played other faction? Would they loose? Would their opponets win if they switched their lists with each other? As for me - not a tool (faction or master) wins the game, but mind and skill of a PLAYER.
In our community nothing changed since 2nd edition. Strong players still wins, weak loose. No matter of their faction. For example in Moscow you won't find any TT in the ranking tops. There are still Neverborns, Arcanists and Guild just as before, as their players didn't loose any skill when we came to M3E.
