It looks like fun! I love the graphical style and the way that each role seems unique while still each managing to look "powerful." The archer and mage in particular looked like a lot of fun.
In a lot of ways, it looks kind of similar to a faster-paced version of PSO2. PSO2's biggest failings, in my opinion, were the lack of true open world and the lack of "synergy" between players (the game played the same regardless of who was in your group; more people just meant that things died faster.) I'm more of a fan of pseudo-D&D style systems, myself, where, for example, a fighter and a rogue are going to play completely different than two fighters for both of the players. If this game pulls those off, I'll definitely give it a try!
