They forgot that tide and doom are heroes they used to favour. They gave too much priority to obtaining prophet. Everything about their draft approach today was not the usual Vici.
I don't even think vici push strat comes from mass summons or wards like they used today. It comes from pugna/razor/ld/dp, with dk/prophet/rhasta/veno picked to complement it. They lacked the core heroes for their pushes today, and getting veno/prophet so early meant they cannot execute their backup weaver/morphing strategies well because they just don't have team fight.
