I fell asleep during I dungeons
I've been playing this game for 3 years and I've found most end game content to be fun and challenging, but can't say that for dungeons.
The way you set it up this month is beyond frustrating. I realized that we have to wait for another 5 or 6 weeks to have enough shards for a 5 star lol. I normally get a 5 star every 10-12 days. I could get more if I grind arena religiously. To get to my point, it's frustrating. I understand I will now get comments of different opinions and that's fine. Unfortunately, for me who has a large 5 star roster it's become boring.
