Change one was Marved for TenZ, then TenZ for dephh, but these moves happened like weeks apart. How is a team supposed to build chemistry if a roster is changing during the season?
Also, the Shahzam analogy makes perfect sense since your reasoning in the original post was because of his chemistry with Sacy and pancada, not his results with Loud. Also, Shahzam cannot be blamed entirely for SEN being bad in 2022, and tbh when they actually got a chance to bootcamp they didn't do that bad.
You're reasoning makes literally no sense because teams can't all start with previous cores, but they can still succeed. Like C9 only had leaf and xeppaa from the old C9, and yet they did pretty well. Conversely, 100T only changed will for Cryo and did really bad. If a team makes a change even if it's just one, the team will need time to build chemistry no matter what.
The change that makes the most sense is johnqt and it's not close. If pancada is going to switch back to smokes, which he's more comfortable with, SEN needs a sentinel IGL, which johnqt is. Plus, if you wanna talk about chemistry, Kaplan used to coach johnqt on Ghost gaming.
