Built-in Parsers

[Taika]

WoW has 2 extra accessory slots called Trinkets. What they're complaining about is that some trinkets became so powerful for a specific class that they literally change your rotation to revolve around said trinket

How does that have anything to do with parsers though? Seems like a question of really unbalanced gear design.

I think the point was without parsers the players wouldn't have been aware they could be lazy and still perform well the rankings so wouldn't have changed their play style.

Sure, but in this case I'd read it as the parser helping to reveal a severe lack in gear balance.
