I hate RNG-heavy progression that discourages playing the actual game.
Path of Exile had terrible loot droprates and gamble crafting when I last played in Ritual League. Starting a league = poring YouTube for safe league starter builds to follow step by step. Gearing up = only picking up currency and buying items from other players on a website. Making $$$ = flipping items (buy low sell high) in hideout (personal town).
Path of Champions (PvE gamemode in Legends of Runeterra) drops shards and fragments to unlock new champions and relics that add a passive effect. Drops are random and not duplicate protected. Champions need 2 star upgrades totalling their unlock cost to feel playable. Optimal progression = speedrunning dailies/weeklies, 2-starring meta champs, and logging out.
