Very high production game feel with one major flaw…

This game’s art design is absolutely stunning! The UI is also designed very well, BUT there’s is one major problem that is really bugging me…the game’s “flow”.

This game’s gameplay needs to be streamlined ASAP, the game is fun but 1/3 of the time is “waiting”, waiting for loading screens and waiting for the attack animations.

My suggestions are to add an option for us to skip cinematic animations and just have a simplified version of the attacks when at x2 speed.

Also, if everything has to be sent to our inbox when collecting, please adds button for claim all items in inbox. Thank you!

Poor ripe off ,

Bad thing

We are put with people who are ahead of you. Finding friends is hard when they give you people who been offline for 28 days or so. So this tells you that we play with other countries and if there is pvp. They will have advantage and you will have to whale to catch up.

It was good until raid 5

I’m stuck on the raid 5 quest. Before getting stuck the game moves nicely. Quest rewards make up for the notable LACK of ways to farm gold and exp potions efficiently. Once they were gone the game got boring fast. 3 days without progress is taking a toll I’m afraid by next week I’ll stop logging on to check.
