Now that N4rrate has been added with Bang, Their Team comp is finally stable and more diverse now. But the question is N4rrate an upgrade from sacy? (with the assumption that Bang IS included and replaces Tenz from this comparison) so we compare them in terms of their individualistic skill and utility value to the team.
Fragging Ability= N4rrate>Sacy , We can calculate this with the recent 5 games of both players and calculate interms of ACS . Sacy had a total of 182.8 ACS while N4RRATE had a total of 248.2 ACS , Do take it with a grain of salt considering that N4rrate has a high ACS since hes been playing duelist in 4/5 games but at the same time he has been the one who has consistently been top fragging while Sacy in the last 5 games have consistently downfragged.
Utility Value=N4rrate<Sacy , The reason for this is that the factor is that Sacy's util usage plays a huge factor in the success of entry from Zekken at going to a site and has been a factor of his clutch capability whilst N4rrate has a great usage in util but more so factors in self benefit which he consistenly achieves.
Agent and Role Diversity= N4rrate>Sacy , N4rrate being added to the team has been not only fill Sacy's Agent roles but fills the duelist as well which open up for more team comps
The winner is N4rrate considering what majorly decides is the factor of the Fragging ability and the consistency of this nature.
