dynamic queue and sunk cost fallacy
https://www.logicallyfallacious.com/tools/lp/Bo/LogicalFallacies/173/Sunk_Cost_Fallacy
Riot keeps trying to salvage dynamic queue, wasting more and more resources on it. I can't remember a time in the 6 years of playing this game that riot actually reverted a change. Instead they continuously modify what is clearly broken, making it marginally less crappy with each revision. Eventually, riot accepts their new change is crap (i.e feral flare, devourer) and scraps or replaces it completely after wasting as much time/resources as possible.
