EvelynnThe recent patch contained a remake for Evelynn that was supposed to greatly increase her viability. However, after an initial burst of play, she fell into obscurity again. Riot is aware that she remains underwhelming and plans to buff her in August's patch.
Before the patch she was less than 1% of ranked games from all brackets and 3-5% of normal games. Her win rate was as low as 28% in ranked and around 40% in normal.
After the patch she had an initial surge of popularity up to 57% in normal and 14.5% in ranked the first 48 hours after the patch. It quickly dropped, however, down to an average of 3.5% popularity in ranked with 10% in normals. While she remains unpopular her win ratio did increase: it jumped as much as 10% in ranked to an average of 40% and 5% in normals to an average of 45%.
TwitchTwitch was a high reward and high risk jungler until his recent remake where his stealth was nerfed. He was put back in the bot lane as a carry. Unfortunately, though, he hasn't found a niche yet: the remake did little to increase the amount he's chosen.
Before the patch he averaged 2% popularity in ranked and 7-8% popularity in normal games. He was around the 45% for win ratios in both ranked and normal matches.
After the patch he jumped up to 7% popularity in ranked and 28% in normal, but it was short lived. He quickly fell down to almost identical numbers to his old popularity, hoving around 2% in ranked and 7% in normal. His win ratios seem similar, barely reaching 50% at their peak.
