Did the nerfs in 5.18 do their job @riot

As we all know 5.18 was the worlds patch, and was balanced for specifically for worlds, as stated here

The goal was to get rid of the 100% pick ban for the worlds tournament, did they succeed? Some may say it is to soon to tell but considering the trends so far, i would say they missed their mark and should of used a bigger window.

So far morde is 100% ban, daruis and barum insanely high pick rates. Garen was bugged (his max health,instead of enemy max health % damage passive) through out public play of 5.18 so i doubt team will be comfortable trying to pick him up. Skarner was picked up once but riot might of over nerfed him. The pundits keep talking about Fio but she is never played. GP from the flash wolves seems to ignore how bad he is played and just does insane damage once he farms IE triforce.

Yes their have been a lot of unique picks in other lanes, which is good, but riot failed with setting up the power levels of the recent changed champs.

So thoughts? I think riot sorta botched their goal here.
