KT Rolster announced the roster changes following the team's successful performance at Worlds 2025. The core of the roster — mid laner Kwak "Bdd" Bo-seong and jungler Moon "Cuzz" Woo-chan — was retained by the club. Top laner Lee "PerfecT" Seung-min will also continue to play for the team.

The major changes occurred in the bottom lane. AD carry Seo "deokdam" Dae-gil and support Jeong "Peter" Yun-su left the team, moving to  DN Freecs . KT Rolster brought back Aiming, marking his third stint with the organization. The lineup also includes 2020 World Champion Ghost, who returned to Korea after three years abroad and switched roles to support. Alongside him, the position will be shared by 19-year-old Pollu, who previously played for  OKSavingsBank BRION  and already has two seasons in the LCK.

The coaching staff remains unchanged: head coach Ko "Score" Dong-bin and assistant Song "Sonstar" Seung-ik have extended their contracts until 2026. Assistant coach Kim "Museong" Mu-sung also received a contract extension.

Despite the stable core, the revamped bot lane raises questions. Aiming completed a challenging season with Dplus KIA, and his previous periods with KT Rolster were inconsistent in terms of results. Similar concerns apply to the support position — Peter demonstrated stable and creative play in 2025, while Ghost is still adapting to the role, and Pollu is leaving his former team for the first time.

As noted in offseason analyses, KT might need time to build synergy, especially in the bottom lane. Having two supports provides room for experimentation, a strategy successfully employed by teams like  CTBC Flying Oyster . The upcoming LCK Cup 2026 will be the first test for the new lineup.

In November, KT Rolster reached the World Championship finals for the first time in six years, where they lost to  T1 . The team has retained the key core that led to this historic result and is building its development around the stable duo of Bdd and Cuzz. The new roster version aims to cement its success in the LCK and replicate a productive run at Worlds.
