There's a lot of discussion about who the most improved player might be, and there have been strong cases over the year.
Such as T1 Carpe. Everyone was hyped for his debut but it was really poor (even as a T1 fan), so much so, people were wondering if he was the best choice. Fast forward to September, and while T1 didnt have the best performances internationally, Carpe managed to be better than he was at the start of the year, pulling of crucial clutches and helping T1 get rounds that were drastically needed.
But even as T1 fan, my choice for MIP is EG c0m. It's a little obvious but also underplayed as to how valuable c0m has been. Even last year, Akrew c0m was considered good, not great. Even when EG signed him, he was considered innovative but not impactful. Even at the start of the year when EG looked awful, there have been talks that c0m was the weakest link and there are better replacements for him. But now, he became a crucial element to EG's success with his impact and innovation on a multitude of agents and now is considered one of the best Sovas in the world.
Read allat and put your choices for MIP.
