Think i’m going to defend Blizzard, i’m feeling dirty just thinking about it.
Classic was not advertised on being content with increased difficulty to give players a challenge in 2020. My guild was one of those that abused the ECTOPLASMIC DISTILLER while it was in the game on the advice of an ex-private server player. Trust me, this made encounters absolutely trivial, it completely removed the threat mechanic. This being present in at least private servers demonstrates bad game or at least failure to correct it and that there were corrected mechanisms in classic.
To reiterate classic was not re-designed to be “challenging” it was designed to be a re-enactment of vanilla as the developers intended at the time. - Have the succeed in every measure of this, if you said no I’d be forced to agree with you.
Now I’m going to have a shower as I feel dirty.
