Servers tagged 1.8 Minecraft usually run on or emulate Minecraft 1.8.x, mainly to keep the old pre-1.9 combat (no attack cooldown, different hit timing/knockback) and the classic feel of that era. You’ll mostly see PvP-focused modes like Practice, KitPvP, SkyWars, BedWars, and other minigames, often with newer client support via protocol plugins while keeping 1.8 mechanics.
