I don't even know why Gen G had a different jungler than Ambition to start! Ambition has saved Gen G numerous times even being the Bengi to Gen G themselves, winning them regional games, playoffs, Worlds etc -
55.357% win % for the jungler that replaced Ambition
63.29% win % for Ambition when these junglers start games
However, you also have to remember that Gen G sucked in the Spring Split having Worlds hangover, per se.
GEN G were more aggressive in 2017
Kills 2017 Spring Split 12.1 kills Deaths 9.0
Kills 2017 Summer Split 9.9 kills Deaths 8.8
- They got worse in the 2018 Summer Split
Kills 2018 Summer Split 8.6 kills Deaths 7.9
Towers taken was something GEN G also sucked in compared to their previous splits
Towers 2017 Spring Split 7.9 Towers lost 4.5
Towers 2017 Summer Split 7.6 Towers lost 5.2
Towers 2018 Summer Split 6.7 Towers lost 4.6
Barons again, another low point
2017 Spring Split 0.98 Barons per game
2017 Summer Split 0.75 Barons per game
2018 Summer Split 0.64 Barons per game
Gen G's journey took a "San Antonio Spurs" type of end - having lost the Finals against the best team in the World(LeBron James Heat -Faker SKT) only to comeback and beat the best team in the Finals a year later. The next year losing in the first round(Groups) against teams like VIT/C9(Clippers).
Casing point -
Gen G's slow methodical style got beat by more aggressive meta style type of teams. Hard to win like that these days in both LCS/Pro scene and in solo Q.
Xayah got banned out 3 times in which Gen G played her once in which teams made it a priority to ban such champion that helped GEN G win games
Ruler as Xayah is 15 of 23 in the LCK splits, playoffs, Worlds and regional games with stats such as 93 kills - 25 deaths and 81 assists but 3/6 banned with also Cuvee's Aatrox in which he was having success on in which it was banned 3 out of 6 also with Gen G won there only game off the Aatrox, as well as RNG playing the Aatrox themselves - Winning against GEN G By the way
