1. Ascension stones rarely drop in expedition 2. Repetitive. Reached lvl 7,500. Same monsters, only stronger. Gets really boring 3. Very grindy in terms of runes. 60% chance for +1? More like 60% to fail 4. Very low chance to get 4* heroes 5. Afk rewards is a joke 🤣. If you want to grind, you have to keep open the app. You wont be able to use your phone 🤣 Dont waster your time 🤣
