I'm playing from 2015/09/28 (from April to September 2017 I worked 10-12 hours 6 days in weaks and didn't have time for normal play, only read story in events).
And I'm tired of game. Reasons (objective and subjective):
1) They forgot about voices in main quests after Palace of Fire. I started play because I like Sali's voice! Yes, they added voices in last chapters "Witch of Ages" [chapters 13-17], but it was after MORE 1 year! And all "Uncharted Waters" without voices (I want to hear voices other Mandragoras).
2) Main story is rare adding and of course without voices T_T. About voices in non main events I don't dream.
3) Good rewards require a lot of time every day even with event's units in events without bonus time.
4) Boring events
4.1) Unfair PVP with unfair rewards. Especially very bad "Call to Arms", plus bad time for me in 3 part pvp events. Fortress Frenzy has better gameplay but rewards same.
4.2) Monotone gameplay in raid, gift and collection events because you should do A LOT OF main quests (or event quests if raid event with event story) for spawn raid bosses or for drop gifts or collectable items.
4.3) New beta event (Rise to the Top) is nothing new.
More than 1 year ago was 1-3 pvp+raid events which was bad for me and other people because this event had limited time for play [it was night for me]. They mix this pvp+raid events and Belly of the Beast and got beta event.
4.4) They forgot about interesting BINGO event which had diffrent tasks for completing. I played only last Bingo (New Year with Son Gyoja) and it was interesting.
Also they forgot about other old events (raid boss events without any story, coliseum events, battle events with non personal tean and with Lil' units team like Lil' Nina, Fionn, Sadhbh and other)
5) They forgot about a lot of 6* units, those cannot be traded.
6) In Ishtarian Idol Season 1 they promised add new version of units which was in first places. Mordred was 4th. I waited ~1 year her new version! And this new version (Remix) was added on Ishtarian Idol Season 2. But for this year other units was added MORE faster and also was added 2 version of Ishtar (New Year and Remix).
Also they added a lot of Guna and 3! THREE! of those new versions were platinum!(yes, she is cute, but she lost and got 3 platinum and Mordred got only 2 new version without platinum). Even Arthur (I dislike her designe) have more versions and got one of platinum! >.< It is unfair. I want platinum Mordred so much!
P.S. Mordred, Sali and Nina are my most favorite units.
P.P.S. And I didn't get new 8* Sali for my 12k crowns T___T
