The epic loot drop rate from Vanilla-WotLK raid trash mobs is pretty tragic. It takes you out of the flow of speedrunning these instances, because you don’t want to waste a lockout. You end up killing literally every mob alive in them, taking what could be a 5 minute raid clear on a speed toon to like 20 minutes.
Black Temple has it, Sunwell has it, The Eye has it, Naxx has it, list goes on
I know the Collector’s Bounty post said drop rates would be looked at based off the first week, and everything is perfect for boss loot - but I feel like we shouldn’t have to get 100% mob count of legacy raids to not miss out on everything.
