I think their main problem was that it was again reliant on the same ramp up that is typical for Pre-Patch events.
The lack of communication in that left people assuming that the current speed of acquisition was all there was, when most likely there was no worry about missing out even if you joined in the last week. People with alts also had a massive advantage.
Could have all been solved with more communication. While you can’t make two first impressions, it still seems like a fun enough event and the rewards are neat. Not enough to play the game just for the event, but I doubt that that’s ever the intent behind these. They’re just there to set the mood a bit for the upcoming release.
My first leveled Tank was Gunbreaker, my first leveled DPS was Mechanist and I am myself now working on Sage to fill out my “shoot guns at it to solve your problem” Trifecta.
