Except other new players genuinely in need of assistance might stumble across the post when searching for information. Doesn't hurt to reply and share information to help out those future adventurers. Even a troll can spark constructive discussion.
The quest in question definitely is a pain in the neck if you're undergeared, which a new player likely will be (you're not going to have level 35 gear when you're still on the level 24 MSQ). There are a bunch of non-aggressive ringtails not related to the quest at the same location (not to mention it's a spawn point for Cornu), and it's easy to accidentally hit them as you're trying to kill the quest ringtails. Instead of just fighting 3 at a time, you can find yourself fighting 5-6. A new player has no idea what's about to happen so they're not going to think "maybe I should clear out some of these other creatures before I interact with the quest destination". They almost may not think to immediately move to a spot where the other ringtails are less likely to be aggro'd once the quest ringtails are spawned.
