PROMOTE BETTER INGAME EXPERIENCE

I would like to propose the improvement of user experience of the game. I have several points in mind: (REVISED)

1. Dungeon Battle should have a x5 Speed option, its to long to do 60x dungeon+20 dungeon in one day
2. Treasure chest is basically not worth it. Need to change whats inside. No more UMY. Exp guaranteed or Even $Kara is nice.
3. Weekly updates for reported card error/bug. This will affect the Kara market price.
4. PVP tournament now is not too effective if u want to burn UMY. only top 50 maybe using UMY to maintain position, as the reward is less than whats invested. Maybe u can change into 20 max games with 10 UMY per extra match.
5. Add Option to Rebirth Kara and get UMY back but locked only can be used for Evolved. (Mods said it's coming)

Thise are my 50 cents on this game, consider the user experience that i think will make this game better played and enjoyed by Fellow Karastarer..
