Woops, I didn't write a review on this one?
Thus I, too, am to blame this gem didn't/doesn't get the audience it deserves.
Yes, I also don't trust Free-to-Play games. I don't like the business model and I don't like the way their gameplay mechanics function.
This, however, is one of the few games which are TRUELY free-to-play. This game is so fair you almost feel bad if you don't pay anything (maybe that's how they get you to spend your money... ♥♥♥♥♥♥♥s!). The things you can buy are purely decorative except for cheap extra space in your item chest (but it's already so big you don't even need it if you just play through the game once or twice).
So yeah, what you get absolutely for free here is a full game and there's nothing that feels cheap about it. It does have a rather classical feel, though. Actually, this is the only other game which gave me that Diablo II feeling. It's not the same and Path of Exile has a lot of good gameplay ideas and a whole fantasy world of its own, so don't expect a clone.
It's been a while now that I've played through it and I cannot really point out any details about what I liked especially and what bothered me, but I do remember I had a good time with this and if you liked Diablo II you should really give this one a try.
Because it has had some big updates and new content since I've stopped playing I might pick it up again soon. Maybe playing alongside you guys because co-op playing works quite well also :)
