Hero meta exists (this is where the game's "tier" thinking lives, not the biomes). Rankings shift by patch and sources disagree somewhat; Rosie is the one consistent top pick. Synthesis as of patch ~2.5.500 (July 2026):
S-Tier (meta-defining): Rosie (DPS carry — AoE + self-heal, scales with fight length), Nikola (main tank — dual stacking self-shields), Tara (team-wide DEF buff keystone), Layla (top support, best placed frontline), Freja (SR fighter — double strikes, shielded AoE), Tarzan (backline-diving DPS).
A-Tier (strong substitutes): Maddie (hybrid damage/heal), Ray (AoE PvE, campaign), Sarge SR (boss/long-fight DPS), Travis SR (boss DPS), Tara-adjacent buffers.
B-Tier (early game only): Chef SR (early tank/heal utility), Ghost (tank, falls off), Eva (mid DPS), Lucky (resource-gathering utility).
C-Tier: remaining/filler heroes — avoid long-term investment.
Note: Pocket Gamer's list emphasizes Rosie/Freja/Layla/Tarzan at S; Packsify's whale-focused list emphasizes Rosie/Nikola/Tarzan/Tara/Layla. Both agree Rosie is the top single-hero priority and that SR/Rare heroes are filler long-term.
