I'm worried about polish and production values of a game made by a company which can't even film a proper trailer.
At a glance, it seems like awfully big project for a small studio, which could bring many issues. The graphics look like Sacred 2 or Titan Quest on minimum detail (I would not expect too much even considering they had to lower graphical detail for the video). Also, the graphical style seems to be rather inconsistent.
And I couldn't find anything about this game having multiplayer or not (essential thing for ARPG).
This may turn out great, but my hopes are high for Torchlight 2, Path of Exile and Grim Dawn instead.
What I like a lot is the inspiration from the old Slavic culture (eg. the deities present in the game are actual Slavic gods) - that's something you don't see very often in western culture Even in Central and Eastern Europe, the classical Tolkienesque fantasy dominates (though admittesdly Legends of Dawn seems to hybridize SLavic culture with regular western fantasy - you can see the races are elves, dwarves etc...)
