tl:dr: sen is not done..... (or I hope for the sake of Sentinels fans and the careers of these players)
Yes, SEN are certainly looking like a bottom-half team at the moment with 5 insta-lock ascendent controllers, not a team with THREE world champions, a on the rise prodigy and a esports veteran.
I CAN NOT say that SEN is doing good right now (at all). But in the long-term I think SEN have a very strong roster and coaching staff. Even as early as the LCQ I can see SEN on the uprise and once we get into 2024 and 2025 (assuming they keep the core of their roster) I beleive they are not done. Once Sacy and pANcada transition into the new environment and team and chemistry improves, Kaplan improves as the coach then I see SEN becoming a genuine top 6 threat.
