I played some of the alpha/beta a year or so ago, and had some fun with it. It has a little of that MOBA feeling, while still being unique in its game mode. The stamina system, however, might frustrate some people. Sprinting, jumping, and using abilities all use up you stamina, but even at 0 stamina, you can still use your abilities normally. So, if you blow all your stamina on abilities, or getting to the fight (this doesn't happen that often if you engage carefully, you won't be able to escape or chase. This, I'm mostly fine with. Not being able to jump, however, makes traversing the area really annoying, especially on certain maps. Overall, though, I did enjoy the game. There were only a few characters I liked to play, but they were still varied enough that it didn't bother me.
Also, for those without Windows 10 on pc(like me), you can still get the Beta through the Arc client, you just have to find some place that is giving away keys specifically for that.
