Maybe it's a bit too early to say anything. But as far as the first 2 days go with fractal rush, this event has been massively successful in terms of creating community cohesion for fractal goers and even urging new players to participate who normally would shy away from the challenge.
This is what I've noticed from my subjective experience:
- Log and complete my CM/T4/Rec run around resets, nothing different there.
- But now there is incentive to keep playing for boxes, which are actually worth farming, just right click preview.
- So I began spinning through rerunning T4s/Recs with different groups for the purpose of box farm.
- Get bored there so I join no req CM groups and help teach guys who are learning. This is fun but not so fast of box farm.
- So I just start joining random low tier group postings in T3 T2 T1, helping people with random goals like "doing this for this achievement ect ect" which these groups are getting joins a lot faster due to players having reason to participate in random fractals, beyond just dailies.
- Then I start purposely making "Come Get Carried" groups for low tier fractals, to help people increase their fractal levels. If you're a vet, it's really REALLY easy to speed clear pretty much every fractal 1-25 so long as you have extra players to do the objectives that can't be solo'd. This is actually pretty fast box farm.
- In the process of all of this, while being friendly and not toxic, I've helped at least a dozen players directly within the past 48 hours, correct their builds and understand what they are doing wrong that is preventing them from being effective in higher tiers.
^ All of that is the kind of healthy community cohesion that Guild Wars 2 modes completely lack. The simple design of extra bonus rewards for random fractal runs while participating with new guys, does nothing but encourage patience and friendly communication. Something like the bonus boxes and community goal rewards should become baseline for fractals and even raids. Whatever it is, it doesn't need to be quite as lucrative, but this event is too healthy for the game to be dismissed as a limited event.
