Well I mean, you can. Most people did. The fight's entirely possible to do in 290 left / leveling right side gear. I know this because for the first week that was pretty much the way you did it.
Having no challenges along the way doesn't either. Sometimes bad players need a bit of encouragement to get better.
This has been a recurring problem; the first time bonus for trials is really small and piddly. If it were, say, 100 Verity and at a point when most of us are grinding out tomes like mad for our relic weapon, you betcha people would jump at the opportunity to join in.Otherwise, I agree that there's a lack of incentive to encourage players to stick around and teach and aid in the clear.
