Rammus Rework Steals the Show

The Armordillo is back with a vengeance! Patch 25.12 introduces a major Rammus rework, transforming him into a hybrid tank for jungle and top-lane roles. With enhanced damage and durability, Rammus is now a versatile pick, ready to roll over opponents. Expect to see him shine in MSI’s Fearless Draft format, where skill-expressive champs take center stage. Check Mobalytics for updated Rammus builds to master his new kit

Champion Buffs and Nerfs Shape the Meta

Patch 25.12 targets key champions to balance the meta for MSI 2025, set to be played on patch 25.13. Here’s the rundown:

• Buffs: Zeri and Lee Sin get boosts to reclaim their spots in ADC and jungle roles. Zeri’s attack speed jumps from 10-50% to 15-55%, while Lee Sin’s tweaks make him a must-watch for pro play. Aphelios and Bard also see buffs, with Aphelios gaining late-game power.

• Nerfs: Gwen’s early-game dominance takes a hit with a higher W cooldown and lower base health. Shen and Azir face nerfs to curb their top and mid-lane control, opening counterplay opportunities.

• Sleeper Pick: Twisted Fate is emerging as a sneaky mid-lane threat with Spellbook and Rapid Firecannon builds, perfect for players looking to surprise opponents.
