I am not enjoying this event. Ticket snafu aside, the event quests are some of my least favorites thus far, the constant PvP play feels more like a MOBA than I like, I must either burn a ton of hammers or lose days' worth of honor, the ticket win-to-cost ratio is asininely high, and finally, the need to spend several hours playing non-stop to rank well is a massive detraction from the fun I normally receive from playing DB.
Bottom line. I disliked the Boss Invasion event, but I HATE this event. Please do not run such an event again in the future!
