After spending a long time in limbo, Skarner finally got the attention he deserves in a rework. But it seems the effects didn't last long, as the champion's popularity has already dropped below pre-rework levels.
NEW PATCH 14.16 CHANGES! – League of Legends
As Reddit user bodynasr pointed out in a July 25th thread, Skarner's pick rate in the jungle has dropped to below 0.62 percent, a touch lower than his pre-rework self. According to lolalytics, the champion was picked nearly 90 percent of the time in the jungle role in Patch 14.6, before his rework.
Now, jungle Skarner appears in nearly 30,000 fewer matches, winning just 45.6 percent of them. However, the top lane champion’s popularity has tripled, which may have affected his performance in the jungle, though even there he struggles to achieve a 45 percent win rate.
Both the new and old versions of Skarner were not very successful in winning games, as he never surpassed the 50 percent required for a champion to be considered somewhat balanced. Overall, he had a win rate of around 44-46 percent in both situations, according to lolalytics. In higher elo games, players did considerably better with him, averaging around 53 percent. However, Skarner's high elo win rate has dropped over the past few patches, now even below the pre-rework version, as has his popularity.
