Arenas

Why is philosophers stone and soul devouring shard only obtainable in guild wars when it’s an arena item, which are OP
Limits access unfairly for smaller guilds or solo’ers
Keep them separate
Pls fix this error

Dragon Orb hoard glitching

I can’t find anywhere to report issues but the stupid orb drop will seize up with a connection symbol every other drop and will cause the ball to drop too late.

It’s alright as a passive time passer.

I like playing after work to pass the time but it’s pretty pay to win based.

Nice game

Very fun and challenging

Без надежды на сохранения и поддержку

Всё бы ничего, игра хоть и заточена на донат и на просмотры рекламы, но играбельна.
Однако, при разборе ситуации сброса прогресса учетной записи с поддержкой оказалось, что в игре не работают сохранения, а поддержка, даже при предоставлении всей доступной информации об инциденте, или не в состоянии разобраться в своей же игре, или не имеет на это желания, постоянно ссылаясь на какой-то второй аккаунт, который им нужно предоставить, чтобы они что-то смогли сделать.
А по факту, после сохранения и переустановки приложения, произошел сброс прогресса. Причем в гильдии остался этот же персонаж с тем же ником, что был до утери прогресса. У сброшенной учетки сохранились данные о полученных наградах, например в шахте. При вступлении в гильдию новым аккаунтом оказалось, что сброшенная учетка отображается как старая у учетка, у которой видна и сила и шмот до сброса. И онлайн накладывался учетки после сброса и у сетки до сброса.
В общем, крайне не советую надеяться на то, что в случае инцидента с прогрессом, разработчик игры признает критический баг и как-то посодействует в восстановлении прогресса. Донатить, по этой же причине, тоже сомнительная затея, с учетом того, что в любой момент может оказаться, что всё нажитое погибло.
