I found the Solstice of Heroes grind last year so dull I stopped about 2/3rds of the way through and never regretted it. There's nothing this year that makes me think anything has changed, and no reward that make me think the grind is actually worth the effort. I do kinda like the EAZ, but the game-play is repetitive and the rewards paltry. I understand you can get better rewards once you complete the armour, but by the time I did that I'd be burned out on playing and really wouldn't want to put anymore time into the event.
