Hey now, I actually quite like the “epic fight” sigil system! If I am struggling to beat an enemy team at Lv.60 (or whatever, varies by troop restrictions and whatever team I build), spending 2 sigils for a +1.5x stat boost is often worth the sacrifice of one less battle overall, especially if it enables me to reach the next reward tier instead of racking up loss after loss.
“Arena of Valor” is the most boring weekend event to be sure, but the last time it happened I needed to grind kill counts for campaign tasks and in the process discovered Orbs of Chaos in the reward ladder. Now that’s a prize worth me paying attention to. Plus, the reduced battle count from 8 to 6 is +30% friendlier on player time investment. I just wish the Hero was allowed to be on team (with some restrictions) because that was probably my favorite thing about it.
Treasure Hunt is a fun twist on the standard gameplay but I’ll agree it needs some tweaks. In short bursts it’s even kind of meditative, a great way to dissipate the rage that sets in late in events when my team reaches its limit (or just bad board luck happens).
