I just don't get it. I'm a 55 and the events are out of reach for me. I can barely scratch together the lowest tier prizes. I'm at the point of just ignoring them because they're out of reach. You need to do more tuning if you want participation. I'm never going to sit on a thousand shards for three months. Events should give everyone a chance at something, that would make them engaging. They don't even draw me in to purchase energy refills because they're just preposterously out of reach.
That's how I feel about regular events. For the seasonal stuff, like the Halloween thing. You really do need to offer something for EVERY level of player. And certainly, every player above 50 should be taking home at least an Epic. Other games treat these events as gifts. A way to thank players for coming back and sustaining development. It's not much fun to just watch the content creator whales fuse the new champs while they're hopelessly out of reach even for someone who's been grinding DAILY since April.
