In my opinion Zyppan is the most consistent part of NaVi.
The problem is that Suygetsu and Shao have games where they just explode and carry which makes no one realize what Zyppan is.
Shao and Suygetsu have games that are great and they destroy and others that are just good (meh good) while Zyppan is consistently very good (or solid good) while also having some carry games.
