The Charge Beacon events at least have a small updating percentage in the quest tracker, if you have that up. The Arena events just say “Survive 16 Waves” or similar.
Would it be a big ask to have something more visible and part of the combat gameplay? For Arena something like WAVE 12 fading in and out near the top of the screen where enemy health bars are.
If we are going to have more events would it be worth having something that remained similar (solely in terms of communication to the players, not limiting the gameplay they were engaging in). For Charge Beacon I felt perplexed there was no boss-style red health bar at the top of the screen as we charged the beacon, my gut expected that. I’d also be comfortable with a boss style health bar being used for waves in the Arena events too.
The events themselves do add variety to the mono experience, and I look forward to them because they are quick to complete compared to a long fighting map. The variety seems good to me.
