Nobody is actively deriding new players or saying that their experience of actually having backlog isn’t a valid position to currently be in with the game

It’s more trying to draw attention to the fact that
1) if you do have a backlog chances are it’s overwhelmingly biased towards content from old expansions (Bozja/eureka, old fishing titles, old relics that still actually have grinds attached, older deep dungeons etc)
2) not everyone has said backlog because either they did it on patch or they started somewhere within the last 2-3 years and play enough they have cleared their backlog, for those people the amount of content EW has released has just been unacceptable

Whether you do or don’t like a streamer or whether you want streamers to be public with their opinions (I mean if you don’t want streamers to discuss their opinions even on stream what do you even want the streamer to do) these opinions exist and people are getting fed up being shouted down as some minority that came be ignored
