A good example of this I recently show were some people telling Scripe(who was playing Torghast), a player who knows and understands the class to use immolate and some comments were berating him for not using it in Torghast to the point he bursted out about it and called them out.
Meanwhile because he KNEW his class he knew that immolate wasnt worth it when the shard generation from a million infernals he has was enormous and immolate’s damage was irrelevant at higher levels of the tower.
But these people who did not understand the class or the powers simply follow the guide “You must ALWAYS have immolate up else you are bad”, they dont know why you should do this or that there might be cases you dont want immolate up.
And these people are so delusional and believe they are good that they think they can tell a better player what to do, that is a perfect example of bad player who doesnt understand the game but follows meta guides becomes a toxic moron.
