OK, overall I'm still not happy with the game, especially PvP.
But, I do think there's something good about this update. I'm on iOS.
1) Offering now drops new T9 reagents. Even though this should had happened in the previous update, I'm glad it finally came.
2) New tournament info at bottom of Town screen. Although I could live without this improvement, I had to admit it does make it easier to see your current ranking and such. So still an improvement, even though minor.
3) Possible reagents drop shown before entering Dungeon. This info is totally useless to me. BUT! They removed the option to buy potions on this screen! HOORAY!!! Many times I accidentally bought potions due to this, especially when there's network error. So this change brought an unexpected nice surprise.
4) Time limited offer. I didn't get anything, but players on Android China get a 900 gems package with 10 Rune God spins, 1 purple fire ATK, 1 purple ice RES. Not a very good deal, but still a better deal. So this could be useful to some players.
Actually I expected more changes, since 2.1 to 2.2 is suppose to be sort of a big change. But I don't really have any complain about it at the moment. So.... Good Job Glu. Keep improving.
