I dont think it will be a problem for new people.
As they would have to get past the Chrysalis trial first, which posses a much bigger issue.
Uhh, Chrysalis is far easier compared to this one. Way less that's going on, and what you have to do is a lot clearer. (IMO that was a fight that was tuned about right for storyline.) Maybe you had a harder time with it but I can pretty much guarantee that the majority of players won't.

I've never had a single group wipe more than once in Chrysalis, and that was generally due to finding out there were people that didn't know what to do in the 20% phase because the game doesn't tell you there's a newbie.
